Nice work Double checked it again on a fresh install of 1.64. I set up my skill bar in game like this: The next time I log in the skill bar looks like this: The potions are still in my inventory. An almost comical issue from the test, someone reported that an NPC was dead and could no longer be interacted with. It's just a straight duplicate of the Alchemist with a different name and text. The server had been running for about 2 days and somehow he died lol. If you clicked on him he had no health, but was still standing there. I can't figure out how or why and none of the testers have been able to deliberately kill him, but I noticed there is an 'Invincible' check box for entities so I have ticked that for NPCs for the next test version (also added the loot fix, so I'll get back to you on that).
