The issue with mq2melee may or may not be related to custom content, I didn't take the time to dig in deeper to figure that out. If mq2melee was broken on the standard servers someone probably would have complained by now so I'm assuming it's a custom content thing, but it's no matter. I can fix it without effecting the functionality on standard servers.

There is an array that gets created that has just enough elements in it for the default number of spells. C++ will try and do whatever you tell it to though; it's dumb like that, or smart depending on your perspective. So when it is told to access an element that is greater than the number of elements the array actually has it tries to do it. So imagine that array stored in memory as a street with 10 houses on it, and I tell you to go to the 15th house and knock on the door.... You're process oriented so you calculate the width of a house times 15 and then bump that up against the speed you're driving to know how long to hit the gas. You end up driving into the fence at the end of the street.

I modified it to check that the item requested isn't too large for the array.

This problem was in the macroquest core file, MQ2Main.dll. MQ2Melee just triggered the event chain that caused the code in MQ2Main to run. It's plausible that this fix will also repair the crash on death issue. Hopefully.

I still need to modify the other clients but I should have the repair up within an hour or two
