Friday Facts #304 - Small bugs; Big changes

Dear Wube

Since the "mega packet" update MP has been frustrating to play due to rubber-banding and latency. This manifests most obviously when you take a small step and it moved 4-5 tiles instead of <1 tile as it should. This is not always happening, but certainly more than 50% of the time.

I have played on the same server for many months and it suddenly went from "usual MP latency" to "OMG I CANNOT CONTROL MY CHARACTER!1!" from one day to the next. I have asked around and it seems this is commonly experienced.

Is this one of your 28 remaining bugs? if so I would like to upvote that in your backlog if possible ;)

Yea, we have also fixed that for the next release

So G2A gets to choose the auditing company? I'm sure that the auditors will be completely objective and reasonable towards the company that's paying them for an audit!

Its going to be one of the Big 4 accounting firms.

We are down to 28 bugs on the forum. The last bugs are often the ones we have been putting off for a reason, they generally require some more meaningful changes and decisions. That is why this week we have a lot to discuss.

G2A update

G2A got back to us this Monday, nothing much has happened so I will keep it short. They asked if we would agree to an audit to verify the money lost to chargebacks, we said yes, and they said they will start contacting some audit companies, and that it will 'take some time'.

Rail-planner obstacle avoidance

Kovarex was convinced by members of the forum to add someway to use the obstacle avoidance mode of the rail planner. Now when planning a rail path, holding CTRL will make it use the obstacle avoidance ghost planning.

There's a third possibility for why people are buying gifts and selling them under market price - skins are a huge market and it's one of the ways to liquidate money sitting on a steam account. So people can obtain skins (legit ways like loot boxes, gray areas like hosting trade websites, and outright scams like skin casinos and phishing accounts), sell them on Steam market and turn it into actual cash.

Ah, that is an interesting point

Version mismatch - need help!

If build 46132 was released as version 0.17.56, then releasing 46133 should be done as 0.17.57. I wouldn't ever expect to see two releases with the same version but with different build numbers.

The deployment of 46132 crashed midway through, and since the deploy was not completed, there was no reason to bump the version number.

The problem was that it failed after it had already uploaded the Linux headless, so when the next deploy succeeded, the old failed deploy was still in the cache

Version mismatch - need help!

7 days ago - /u/Klonan on Reddit - Thread - Direct

So we think that there was a cache issue with a version of the Linux server, and a few people downloaded an old cached version instead of the latest correct version when updating last night.

So the solution is for the server host to download a fresh copy of the linux headless server

Under 100 bugs

We have a record low in our bug report forum, of only 55 active bug reports. I don't think in the history of Factorio the bug forum has been so clean. No doubt once we mark 0.17 as stable the count will shoot up again.

For this weeks graph I added the count of players on Steam as the left axis. We thought it would be somewhat interesting to see if there is any correlation between the two.

Note: The axis have different scales.

I also prepared the same graph but for...

You are running version 0.17.56 (build 46133, win64, steam)

Server is running version 0.17.56 (build 46132, win64, steam)

Thanks for letting us know, we will look into it

Can you try running a clean install of the linux server and see if the issue persists?

Minor Features

  • Added option to enable Steam Cloud Sync for blueprint library to Other Settings GUI. Please backup your blueprint-storage.dat if you chose to enable it. The option is available in Steam version of the game and Cloud Sync needs to be enabled in Steam for the library to be actually synchronized.


  • Fixed that the blueprint library GUI sometimes wouldn't update until the mouse was moved. more
  • Fixed that deconstructing tiles in the map editors instant-deconstruction mode didn't work. ...

Use the automatic updater if you can (check experimental updates in other settings) or downlo...

The multiplayer megapacket Twinsen

Last month I joined KatherineOfSky's MMO event as a player. I noticed that after we reached a certain number of players, every few minutes a bunch of them got dropped. Luckily for you (but unluckily for me), I was one of the players who got disconnected every, single. time, even though I had a decent connection. So I took the matter personally and started looking into the problem. After 3 weeks of debugging, testing and fixing, the issue is finally fixed, but the journey there was not that easy.

Multiplayer issues are very hard to track down. Usually...
