Looks like the projectile crashes were caused by tf_weapon_criticals 0 simulator. I also had it crashing whenever the Boston Boom-Bringer's sound played (via taunting with the attribute) but disabling TF2Attributes seems to have fixed that as well. Could've been something else that I'm using with TF2Att, though.

Simply spawning a tf_zombie seems to precache everything needed without error. Doing so won't completely lag the server or clients, unlike doing the same with Merasmus.
My Windows server is running an old version of SM, which is probably why that simulator crash is happening.
