No real idea on this one! Please do a full **clean** re-install:

- move any valued save games elsewhere, and user_empire_designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races.
- "uninstall" in Steam-Stellaris
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox/Stellaris folders
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, before installing again.

BulkySplash said: I have the same problem now with the new Dick update. Wanted to get back into Stellaris now, playing humans. However, the 2 human empires from the base game are missing. "Earth custodianship" from Synthetic Dawn is missing as well, and there might be more missing from my DLC's, but I did not check all of them. I already tried two times uninstalling and re-installing the game and deleting the folders as suggested by @AndrewT, to no avail. Changing the hard disk, as suggested by @AlterNative74, also did not solve it. They are missing whether I play with my DLC's enabled or not. I have never used any mods. Any ideas?!?
In future please don't reopen old threads, thanks.

When you did your clean reinstall did you move user_empire_designs.txt out? You should leave it out while we work on this.

If that is so, we're not going to be able to fix it here! Can I ask you to check if this is posted in the Bug Reports forum yet? f it is please add your voice there, otherwise make a new thread to alert QA and the devs of it. Thanks, and sorry for that problem!
