Playing on PC, Operation on the Nautica map.
My Brawler was effected by "Intimidation" and could not engage in melee combat, the tip for the ability reads cannot "shoot" and if melee attacking is included should state so.
On this map and another before this I have witnessed AI (only Orlocks) throwing grenades at themselves.
Pathfinding for the AI is a little bit buggy as well, a Goliath ganger on this map has done the same circuit twice where he jumps to the centre where the resource collectables are, spends a short while running into crates and then takes an elevator back up to the floor he jumped off of only to repeat this circuit in the following turn.
