Okay so, I got this mod and crafted an item that'd add 100 to the max. carryweight, which at first set it up to 400 and worked all fine. Though, the second I saved and started the game again later, it'd be down to 300 max. carryweight, and if I removed the item it'd be 200. Is there any way to fix this?

TL;DR - Pouch that should add 100 max. weight ended up removing 100 of the vanilla carryweight
