I have recently updated to 634 from 567 having tested certain levels with different scenarios I've found the following issues to be recurrent:- - creatures will not attack an enemy Dungeon Heart when placed to the West of the heart - Ally players doesn't work - most experienced creatures not being picked up from picture (also in 630) - you're unable to use spells on prisoners (also in 630) Parties have been fixed (from 630) (630) http://keeperklan.com/threads/2886-Nighly-Builds as mentioned here.
