I have posted about it on oxide, but looks like, it lost.
The problem with /rec i suppose, was 0.1 sec timer to open the box. If chat wasn't closed, then opening the box will end up with instant firing the "endloot" event, thus deleting the box, and setting cooldown for another use. I guess, that chat isn't closing in 0.1 sec sometimes. After increasing to 0.2, i haven't noticed any problems.
