1. I just noticed that my ring of economic bases about a core world has rotated counter clockwise by two hexs, and I lost a base due to it being next to a star.
2. If I scroll through my core worlds via the planet tile screen, some of the thumbnails for buildings disappear.
3. Occasionally, the game goes into a really severe lag. i9-13900K, NVidia 4090, 64 MB RAM
1. They will need a save file from before the shift.
The current save could be enough although I suspect you will have to start a new game and be able to get a before and after save.
2. Known bug they are working on.
3. The larger the map the more AIs the slower the game gets in later turns.
