When I played last saturday, conditions like burning, poison, slow, paralyzed, etc... did not appear on the models when we attempted to add them. We ended up using labels to manually show these conditions.
The mark as moved and cleared moved also appeared to be misfunctioning. At least we couldn't tell if they were working.
I can check my version of the vassal engine at this time, and I'm using a Mac, so not sure if relevant to csonti's post.
