I thought I'd report one bug I had where a character (Wyll) could select actions but not take them.
He was able to move but after finishing his turn he returned to the spot he started. He would begin casting animations but then the spell would not hapen. This happened around the
section.
The only unusual thing I can note was that
is a follower (following a different character) but did not enter combat at the same time as the rest of the party. The bug happened after he joined the combat partway through.
