Potential bug when targeting with a range [RoF2]

My macros will occasionally crash, and I think it has to do with using /target with a range.

I'm playing on PEQ, and there's a rule there that you can't use /target across the zone, so I added an MQ2 alias: /target=/target radius 200. The crashes are intermittent (it maybe happens once per half hour on one of my casters). I haven't tried reproducing the issue without any plugins loaded or without my macros loaded, so I'm not 100% sure that the target is the issue, but I don't remember it crashing before I added that alias in, and after I went back to target without the radius, I haven't had any crashes.

I'm using the most recent PEQ RoF2 MQ2 compile (from March 11).

I attached a debugger and got the debug output a couple of times. Pasted below in case it's helpful.

Let me know if there's anything I can help with. It's not a huge issue for me anymore, but I thought I would post here in case there's a bug that's affecting other folks.

Thanks!

Thanks for the thorough report, next time I have rof2 loaded I'll spam it with some /targets and see if I can get the problem.

Thanks!

Some additional detail about when it happens:

* It usually takes about a half hour of regular playing with a 6 box for someone to crash
* Usually, it's one of my casters who crashes. My casters do a /target id some_mob_id when nuking.
* Sometimes, all three casters will crash at the same time, which makes me think it might have to do with some global state. Sometimes, it's only one that crashes, though.
* My looters also sometimes crash. I think that they usually crash at the same time. My looters do a /target corpse radius 100.

I vaguely recall some issue with targeting corpses. When your casters crash is it possibly because they went to cast a spell on a mob as it died, resulting in them targeting a corpse?

That might trigger the issue sometimes, but I don't think that's the whole issue.

If I recall correctly, the casters often crash in the middle of a fight. At least, when I look at the last frame of their screen that properly animated before everything froze, the targeted mob is often partway dead.
