Had a weird bug (more like a series of bugs) last night... (Commander Ironman)
VIP evacuation mission (the one where you have the VIP at the start and just need to get to evac)... We all started out atop a building and on the first move to the buildings edge spotted the first pod - an Andromedon, Shieldbearer and Elite Trooper...
So thinking I can capitalise on the height advantage I move everyone to the edge of the building in a big long firing-squad line... I'm reluctant to use all my explosives on this first pod as I suspect a Sectopod or other nasty enemies are ahead, so I take all my shots, Shieldbearer down... Andromedon ends up with about 1 pip of health; I figure he can't climb the building so the worst that will happen is a pot-shot at one of my guys... Unfortunatley this was the first time I hadn't taken this enemy out on the same turn I engaged it...
He charged into the building, smashing most of the wall below us to pieces... then threw an acid grenade which hit the entire squad (luckily the VIP was further back) for about 5 damage, shredded all of their armor and then the entire front half of the building collapsed and they all fell taking further damage (plus were all acid-burned)!!!
It's a miracle nobody died, but it wasn't looking good - all I'll say is I've never been happier with my decision to take the specialist perk which heals everyone on the team!!!
However with that out of the way, something about the combination that happened with that attack glitched things out a bit - I had the usual "road-runner" effect of half the squad hovering in the air until they suddenly realised they had fallen... but several of my squad had no animations at all for the rest of the mission... They could still take their turns as normal, but no animations would play; clicking to move them would see them instantly teleport to the destination... firing would incur a massively long pause and then all of a sudden the damage etc. would happen. Very weird
Oh and a few minutes later I failed to hack a Sectopod, increasing it's armor and health (great, I thought) it suddenly said "hack successful" at the start of the alien's turn and gave control of it to me anyway!!
