After a while things stop spawning. Monsters. Loot. SOUL STONES !!!!
After a while my priest cannot cast his ahhh.... 'holy bolt' spell I think it is. Top one on the left hand column of the offence skill page. I can get it to come back eventually but once it goes it comes in and out of service a lot. Easier to restart than put up with it.
Pretty cool game though. Thanks to the devs.
