I was playing 3 am CST to after 7 am CST this morning - few bugs - tree's growing in water and inside of rocks; baskets may or may not open. Population explosion of Hamsters
Originally from Rutgrr, to fix this problem you go into your xsyon folder: Xsyon/Bin/Xsyon.exe and delete it. Then run the Xsyon Launcher and it will resolve the Incorrect Game Version issue. Worked for me on the first try!
