Hi,
I've tried this several times and I'm convinced there's some sort of queer bug, at least in the latest Alpha version of KeeperFX (don't know about other versions). I cannot get very far into Morkardar without the entire game hanging. I have to Ctr-Alt-Delete and sign out just to get out of the game; trying to kill the program doesn't work.
There are also sometimes tell-tale signs that something isn't right; the first time I played the level tonight, several bizarre things happened: I actually made it to the enemy heart and "destroyed" it (it wasn't actually destroyed or even damaged (even though I had bashed it to pieces and had actually got the "You have defeated an enemy Keeper" message), but the game said it had been destroyed. Also, all blue's territory remained). The training room posts stopped spinning, and the chickens in the hatchery became stationary and motionless. Some of the spells in the Library were spinning really quickly, and others stood still. Just now, before my game hung, I noticed that the red smoke that appears when an Imp fortifies a wall didn't disappear, but was hanging motionless in mid air. The last 2 times it hung, it was when I possessed a Horned Reaper. Bear in mind that this is just minutes, if not seconds, into the game.
Looking at the log, I see an awful lot of "Infinite loop detected when sweeping things list" errors. That can't be good. I also played another level, which worked fine and with no such error.
Nothing like this has yet happened on any other level I've played (not that I've played the majority of them), but it seems to me there's some sort of bug. Surely the game shouldn't be crashing under any circumstance? Has anything like this happened to anyone else?
Could this have something to do with the neutral Horned Reaper being tortured in the neutral Torture Chamber, something that doesn't happen in the original game. Also, part of the multicoloured fire is stationary, despite there being another multicoloured file that isn't and goes around the room as it's supposed to.
