That is blastcore, yes.

Aliveserver was ran as a server mod today. Crash happened once again.

ACEAdvCPR and the other medical mods are 100% compatible because we do not use the newest version of ACE because of its butchering of the medical system and we will not use it until it is fixed.

We don't know if this issue is even ALiVE related anymore. Earlier today we ran a different mission (a modified Evannex scenario) and the error happened again; player joined the game and we received the same crash at the end. It could be ACRE, VCOM, or any other mod at this point.
