Tried to use the bug template but it didn’t work. So here’s the jist of it.
While interacting with a Golem’s inventory, players can accidentally equip their armor to the golem. Doing so has no effect on the Golem itself, but the armor is unable to be seen in the inventory. The only way to retrieve the armor is to break the bond with the golem, or equip a different armor set, booting the previous out.
Not sure if this is an isolated problem but thought I should report.
Have you tried recalling the golem? They should drop what is in their inventories when recalled and therefore should have a loot bag in the spot they were in prior to the recall.
