First bug: When an explosive weapon (M79, LAW, Flame Arrows) is fired at a collider, the explosion turns into a nade explosion. (I'm not sure if this is intentional, but it seems strange)

Second bug: When an explosive weapon is fired at the point where the collider intersects the polygon, there are 2 (nade) explosions instead of 1. This bug doesn't seem to happen with nades.

Note: I haven't tested either of these bugs online.

Okay, I just went and tested both of this bugs online and offline. Both does happen, although the second bug is kinda hard to reproduce.

Great findings Bmanx2000

There's more than one kind of explosion? I don't get it...

The nade explosion is bigger (at least, the graphic is bigger) and uses a different sound. Try it yourself and see.

yes there are...just try shooting a m79 and watch the explosion, then throw a nade and watch it. There is a difference..
