I'm fighting my way through the "training" dungeon and every time the cave collapses behind us, the game freezes. Any ideas on how to fix this?

Exact same issue. Guy says something about not going back that way, game hard locks. Every time.

I got past this by running through and down the stairs as soon as the drawbridge drops -- away from the tunnel mouth. Standing anywhere near the guy or the tunnel where the collapse is causes instant hard lock.

The same thing is happening with me, same location too.

It seems to be cause by that shaking effect caused by the dragon, like before you go into the potion room.

yep i can confirm this. standing next to the tunnel or the guy will freeze the game. solution is to run further away.

Were do I run too? If I only have 5 seconds after getting into the room, I need to know which way to run.

I'm actually reinstalling the game. So I wont be able to try anyway for another half hour.

Here's how I fixed the problem.

I was always pulling the handle to lower the bridge, when I let the other guy pull the lever there was no crash.

So, don't pull the lever yourself.
