"Explode" mod on boxes

There is a thread about boxes but here Im talking about certain mod. "Explode" creates a delay sometimes even more than 16 sec after killing all the monsters from it, more than 16 because my Blood Rage lasts 16 seconds and it expires sometimes before box is opened, annoying to wait for it to be finally opened

Yeah, have had this happen more than a few times, and sometimes the explosion doesn't even happen even though the long delay does.

And you cant go kill other monsters and wait the chest to open while you killing the stuff, because it wont open, you have to be near the chest and wait that 16 secs near it
