Parasites, MC and build limits

I've created a parasite mind controller (with perma-mc, but this may not be related) with a build limit. First of all, such unit has absolutely no means of surviving the destruction of the vehicle. It is basically a one-time unit. SuppressionThreshold does nothing, perhaps because mc parasite is not the one dealing the final damage, ever.

Also, when this unit is destroyed inside the unit it parasites within, build limit will not unlock. Apparently game thinks that the unit is still in play. I haven't tested how this affects short game, I will soon and post the result in comments.

I have a parasite-based Chitzkoi infantry that has a build limit, but I haven't run into the no-unlock issue with it yet. Perhaps it's related to the fact that it's a damaging parasite weapon. If I do encounter problems with it as well, I'll mention it in the comments.

This bug is most likely not related to Ares.
