Information: How to prevent crashes when cancelling upgrades.

Tip: How to prevent crashes when cancelling upgrades.

I was about to post a question about this, but I managed to figure it out myself and decided it was just obscure enough to post about. It was a strange crash bug I had, and others might benefit from knowing about this.

I had a pair of structures. 'Trap Marker' and 'Concussion Mine'. Essentially, the Trap Marker could be upgraded to the Mine. (And other things, but that's not important)

The catch was, when you cancelled the upgrade, WC3 would crash to the desktop. You could cancel the Marker, you could kill the Marker AND the Trap. You just couldn't cancel the upgrade.

Turns out, I had a conflict with the pathing information. I'm not sure why WC3 cared about this, but this is what it to fix it.

PROBLEM:
  Trap Marker
     Pathing Map: Circle of Power
     Collision Size: 16
  Concussion Mine
     Pathing Map: None
     Collision Size: 0

SOLUTION:
  Trap Marker
     Pathing Map: Circle of Power
     Collision Size: 16
  Concussion Mine
     Pathing Map: Circle of Power
     Collision Size: 16

I can't tell you why it works now, because i'm not sure. All I know is that's what fixed the problem.

The upgraded form had no pathing, where the upgradeable form did.
Returning from the no pathing to some pathing by cancelling the upgrade probably caused the crash.
(Since the game must have gotten confused about whether or not to make it pathable)

Yeah, that seems to be it. Not sure why it tripped it up so badly, but it did. If you're having problems with WC3 crashing when upgrading structures though, this is something to watch out for.
