Rocket Detonate Self-Kill Crash

[XaserAcheron]

Summon an ArgRocketLauncher, give yourself the Remote Detonate mod. Fire and immediately detonate, killing yourself... and ZDoom. :<

I could very well be doing something bad in the ZScript code, but an outright crash is suspicious enough to warrant a ZDoom bug report.

While writing out the post, I kinda got an idea of what the problem might be, so it may be a "fix it yerself." Will tinker later.

Unfortunately, the simple fix didn't work. I'll probably just go all-out and move the rocket stuff to the weapon like I'd wanted to do anyway, which will hopefully shadow-fix it.

Fixed now, I believe. The Overlay was doing Weird Shit(tm) but I think I've ousted the oopsiness.

Will reopen if for some reason it comes back.
