Merciless breaking off before complete

Is everyone getting this? There is a bug in Vader's merciless that I see more and more. Happens against Padme leads and against Revan. The bug is simple - Merciless breaks off without completing. Usually it happens after Vader defeats an opponent and 1) JKA takes a bonus turn or 2) a character is defeated under Revan and is revived and takes an immediate turn. The characters that Vader did not go against keep the Merciless symbol, but he does not get to finish.
Just happened without a character being defeated. I still had one to go.
