Hmm... that sounds really weird laugh. The mod is still enabled right? If it is enabled, then it is possible that those specific crates/boxes had modified loot, but if it is most crates/boxes around Silverglen then I guess the module is not really working :P

If you are not getting loot from these boxes, then the module is likely (for some reason) different on your PC or inactive. - that would be my first guess anyways. (Damn, not very helpful in troubleshooting xD)
