Having saved a game (either manual save or abort) and then resuming it, the connected player(s) inventory dissapears. Both the combat vest and any backpacks carried are empty. This does not apply for the host, which does just fine after resuming.

We noticed that the white capacity bar for vests and backpacks are gone after resuming. So our theory is that they reset to zero capacity upon resuming, hence loosing all gear inside them.
