So we've had 2 crashes in the last 2 weeks that were different players fireballing their own simulacrum. I've tried to repro on the test server by creating one and then killing it over and over without a repro. What do you guys use the simulacrum for? Something is going on during its lifetime that is causing the game to crash when it dies.
Rumor has it they were a partially implemented project then abandoned for some reason. It did provide a new spellbook that Shyla had to get for all the newbies... To my mind, something that is a copy of something, creates possible in game exploits... and possibly null pointers...
I think it has something to do with the fact that simulacrum upon creation is mastered to caster, then you are familiaring it and dispelling it, removing master. Maybe there is some code that is called on simulacrum death that expects to find master(%c) and doesn't because it's been nulled out by familiar/dispel.
