I started up my 65-hour Ironman Stellaris game on Sunday to find rampant unemployment and economic deficit. A lot of the updates seem cool, but not a good fit for trying to continue a game that's almost complete. So I followed the instructions to revert to Butler. Mostly back to normal, but with a couple oddities. I could swear the icon for amenities is different than I've been playing with, but whatever. I'm seeing a lot more non-green planet icons on my galaxy map, which is weird because I have a pretty multi-species empire at this point. When I check my species list, the reason is clear: I have no species in my empire whatsoever. It's like that no matter which version of the game I load it in. If I look at population details for my colonies, they're all blobs with no species name. Is there any way I can recover from this apart from having kept a backup save (which I didn't)?
On a related note, the first time you load Dick, when you go to start a new game, there's a warning that your old save files are not guaranteed to be compatible. If you start the game with "Resume" from the launcher (the faster way), there is no such warning. It seems like if the save files aren't going to be compatible, maybe you should let us know when loading the save file? Or at the very least before overwriting the save file.
