after i made an improvised backpack i started to see an item dsync (might be low server perf causing this?) because my axe disapeard from my hands and back but i still had the item in my hands .
So tested throwing it and i saw where it landed and tried picking it up again and it was in my hand but i could not see it (it was still displayed on the ground).
