All in all, after looking at 2 hours of 4 men runs, I have to say it's somewhat buggy but not enough to take us out. Let's just say we'll need to wait for the real deal from the next stable DB release. I am quite happy that it works for most of the parts. Gambling is still buggy of which I thought it was fixed, based on solo runs. Not quite the same scenario in 4 men.
I went ahead and just updated to version DemonBuddy Beta 1.1.2914.596 as suggested, and it looks like it's doing a lot better. My friend who is sitting in as the 4th player temporarily (who was watching it mess up before) says it looks like it's running a lot smoother when surrounded by monsters.... if I notice anything change/bug out again I'll let you know asap. May be going to sleep here soon though. Appreciate the updates.
Regards
