There seem to be issues with custom maps, at least with this one and olympia. We tried out both and every time at least 1 of the 4 players was having issues that forced a restart with a working map. Game behave strange with major bugs on gold, imps, creatures standing still doing nothing, rituals, everytime is an adventure with something not working. This do not happen with official maps it could be some of the game updates maybe changed something map related that needs to be updated in the map, I dunno.
