Cities: Skylines Dev Tracker

Make sure your pagefile is enabled and set fairly large. I recommend setting the max size to 32GB. The game might simply be running out of memory because the pagefile isn't large enough.

Are you using any mods? Or is this happening in a city without mods (not counting the mods that come with the game, like Unlimited Money or Unlock All)?

Always make sure to disable any mods you don't absolutely need when using any of the editors. Most mods are made for the simulation, and they do not work right inside the editors. You might simply have a mod, that has messed with the map file as.

If you don't need any mods for the map, then using the launch option -disableMods is the easiest way to do that. If you need some mods and assets, but have a lot installed, then it might be worth setting up a 2nd Steam account and only subscribing to the mods and assets you need for the map on that one. You can use Family Sharing to share the game with that account, so you can swap between 2 sets of workshop subscriptions.

With no mods or just the ones you need for the map, try opening it and see if that works. If it doesn't, then it's possible the map file has been messed up by mods, that shouldn't be used in the editors.

Ah, so you're also changing the type! I completely missed that in your post. That changes a lot of things, as that's generally a bad idea to do with Ploppable RICO. I haven't tried it with the new one, but the old version of the mod couldn't do that reliably.

If you don't have any other buildings, you have RICO settings for, then the easiest way to reset them, is to delete the LocalRICOSettings.xml file (go to local files through Steam to find it). If you have settings for other buildings you want to keep, there are 2 ways to go about that.

You can do it in game through the settings panel, which will be easiest if you remember the names of the buildings, but you can also just browse the list until you find them.

Or you can edit the LocalRICOSettings.xml file in a text editor like notepad. This is a little more complicated as you can mess up the file if you delete too much or not enough. Each building has a line with all their info, which just delete to ... Read more

Looks like you might have Citrix Workspace installed. It doesn't work with Unity games, like Cities Skylines. See this thread for some workarounds that will hopefully work for you.

The tram tab should be next to the trolleybuses - it's just been pushed over one space.

If you don't see it anywhere, try verifying game files and making sure the Snowfall DLC is enabled in your games library.

A lot of mods aren't made for the editors, so they break a bunch of things. Make sure you disable all mods you don't absolutely need before going into the editor. If you don't need any, then you can use the launch option -disableMods to easily turn them all off.

Just remove the RICO settings for them, so they turn back to growables. That should do the trick

Oh, I think I missed that you were looking to dublicate them. In that case Building Theme's clone option would be a solution. It needs to be enabled in Options (and you might need to restart the game before you can clone). After setting up the clones for different levels, you then need to restart the game for the clones to be loaded. But once that's done and set up, you can have those growables for any level you'd like.

Safenets should be able to fix the error in there from Crossings.

If that doesn't do the trick, try the Loading Screen Mod's Safe Mode option.

Does it happen on just a specific save or also on a new game?

I see a simulation error in there and an error from the Pedestrian Crossings mod. The SafeNets mod should be able to fix that (Loading Screen Mod's option to recover from simulation errors might also do the trick).

This asset is failing to load - probably due to needing Larger Footprints mod.

Interestingly there's no crash in the log, but if the simulation error caused it, hopefully SafeNets/LSM will do the trick. :)

If you can post your output log (player.log on Mac and Linux), then we can take a look and hopefully see what's happening and what's causing it. This guide explains where to find the log and suggests some sites to upload it to, since we can't attach files here on Steam.

That could explain it. It looks like there's a little bug in 81 tiles, that causes underground metro to be lowered every time we buy tiles. If you are still missing some, I would get them now before fixing your metro, so it doesn't sink further. :)

It could very likely be the game is running out of memory then. There's a few things to avoid that. First I would recommend you set the max size of your pagefile to 32GB and make sure there is that much free space on the harddisk, the pagefile is on.

That might do the trick, but you might also want to look at your workshop assets, and remove any yo... Read more

What happens when you try? Does it crash? Does it just load forever? Are you using any workshop content?

To see what's happening, we'll need your output log (player.log on Mac and Linux). This guide explains where to find it and also suggests some sites to upload it to, as we can't attach files here on Steam.

Do you have 81 tiles perhaps? And did you perhaps buy a new tile before this happened?

No, many other stores sell codes for Steam as well. Paradox Plaza (the publisher's store) for example will send you a code, which you then enter into Steam. Just make sure that the place you buy it from is selling a Steam key, as the game also comes in a few non-Steam versions.

As far as I know this happens with 81 tiles. Every time you buy a new tile while you have the mod, the metro will sink. The best option is probably to unlock all tiles with the mod first, and then build (or rebuild) the metro. At least until it's fixed.

Can you take a screenshot zoomed out more? So we can see more stations and the lines that aren't reachable?

You might be hitting the vehicle limit, at least that's something that people sometimes see when hitting the limit. You can check how close you are to the limit with the CSL Show More Limits mod.
