To add on to #395 , any mod that has item capabilities has their capability seemingly nullified and reset whenever it enters a players inventory. Tested with Iron Jetpacks and TerraFirmaCraft (Unsealed barrels, lamps, water jugs all default to empty. Weirdly, sealed barrels dont change.)

This is a major game breaking bug that means Origins forge cant really be used.

I think that I know the culprit code, it couldn't be anything else.

Fixed for upcoming update.
