Hi! We strongly recommend that you finish any ongoing games before updating to 1.5 Banks. Here is how you continue to play on an earlier version of Stellaris: 1. Right click the game in Steam 2. Go to Properties and select the tab called "BETAS" 3. Pick the version you want to play and close. 4. Allow the game to update 5. Make sure, before you load any save, that the version number in the game is the one you want. 6. If the previous step fails, exit the game, right click -> properties -> local files -> Verify integrity of game files and wait for all files to be verified before going back to step 5. You can freely swap between the latest version and previous versions this way. By selecting "NONE - opt out of all beta programs" you go to the latest released version.
