There is an annoying thing in this beta – current turn not finished for a battle brother with 1 and even 0 ap remaining – you need to hit the end turn manually and they are remain in the order line to finalize turn. It takes time. There was no such issue in a previous beta – when 1-0 ap remains, a turn was finalized automatically.
I think they moved this to game options, check out gameplay tab im pretty sure i saw something like that there.
