Thought I'd post this here for starters, because I'm unsure if it's actually something in the ST:R files causing this. Only seems to happen when Shivans are getting shot at (the only observed event), and it essentially happens whenever the hell it wants. The crash has been observed while Basilisks, Seraphim and Nephilims are in field of play. There is no error message; just the generic Windows crash notification.
[EDIT] Crashed again, this time with no shooting happening, as bombers (probably Seraphim) arrived in the same mission, Field of Destruction. The crashes also occurred in the prior mission, but a restart let me finish with no issues.
[EDIT 2] Latest nightly debug just threw this up in Cloak and Dagger. Nothing in debug about non-ships with subsystems.
Assert: "objp->type == OBJ_SHIP"
File: ship.cpp
Line: 12738
