I downloaded the most recent version and noticed that there still is a bug of AoE.  Whn an NPC applies an AoE effect and then the PC follows up with an attack or ability, the game freezes: the turn does not end and other NPCs can't act, whether on the player's or the enemy's side. I noticed this after applying Black Tendrils, Cleave and  and Overgrowth. 

Can you give more details/save files on how to replicate it?

There appears to be bug with rearranging active battle group as well. I don't know what's the exact condition to trigger it, but often when I try to switch backup characters to active role, the character doesn't change. If I want to change the active character, I have to send the active character back, and if I bring the character I'm trying to switch out back, they auto replace the character I'm trying to switch them out again.
