i am not sure what exactly the problem is
is it that a cyberdisc that stand besides another cyberdisc dies if one explodes?
thats solvable by reducing power in the corpse item or reducing the damagmodifier for HE in the armor
"The vanilla Cyberdisc is having a problem. Whenever it dies, the corpse goes with it." thats vanilla behavior iirc so whats the problem here?
perhaps you could increase the armor values of the corpses if you want to keep the corpses after explosion
The problem is that the Cyberdisc corpse has, essentially, 0% chance to survive the blast that it leaves behind. I've tested this over 10 new battles with sectoid terror ships. Not a single cyberdisc corpse survived. And no, I'm trying not to kill the Cyberdiscs with explosions (Using plasma/lasers) but they still don't survive the blast. I reset my game to default, ran the test again and several cyberdisc corpses survived (All but one, but I believe that it was because the cyberdisc died in a doorway)
I'll keep trying, but the point is so more cyberdisc corpses survive so that you may use them. The XCOM Cyberdisc mod is nearly useless if the cyberdisc corpses rarely, if ever, survive their own blast.
