Unable to level up a player with +1AG

Playing BB2 on Steam. Multiple people are having an issue with leveling up players after rolling an 11. When you select the +1AG and press OK, the game says 'Error processing player skill". This issue seems to stem across multiple teams, most mentioned Amazon, Orcs, and Skaven. This seems to be a bug.

Known bug which appeared yesterday. Cyanide should be looking at it today to my knowledge.
