This is a weird battle. Apart from the fact that the small portraits for the young maple trees were missing, somewhere in the middle of the game the monster drew only two cards. This happened after an acid blast forced a double armor discard. Attaching the log for debug. Hope it helps. edit: well well well, I didnt notice it before so perhaps this isn't a bug at all. I'm in another tree adventure and its drawing 3 cards initially and then somewhere along the way they started drawing 2 as well...
"They" started drawing 2? So it's a group of minions, where the draw numbers depend on how many are left alive?
