old saves are
not compatible, checked it out. done the full wipe on the previous install, manually wiped saves from the box, ran "delete saves" and "delete persistent" from ingame menu just to make sure no remains. no bugs/crashes so far but still early in, don't even have the map yet.. what?! it's Teh Summer. some people do play outside.
P.S. the game still lags, if just a little less, at least the rollback doesn't freeze anymore.
apart from that, sad to not have the chibis anymore. i liked them, and liked the option to choose either.
