In v0.2.3: Chasm fixed, winds of decay (and other cone abilities) targeting fixed, crash fixed (save game you sent should work), apprentice casting spells on different z-levels fixed.
Other bugs still on the list, will try to catch them for next patch. I can't seem to reproduce the message going out of bounds, if anyone can provide some screenshot with information about the graphics settings (borderless, fullscreen, resolution) that could help.
