Using a mage caster character I went after the 2 undead spiders. soloing them was not easy but doable. Several times I killed each of them as is correct and normal but then when the spider would get to 5% or very close to it the screen would freeze and eventually the spider and graphics would disappear then I would disappear and lock up. This happened 4 times in a row. There was an update so I tried it again. With other player I know in RL and in game the spider bugged out gain. The spider bugged out several times solo and with others again.

I tried to move the spider away from trees or other items on the map to see if a specific tree or rock or plant was glitching the spider but it did not change the effect of the spider.
This same issue took place with both undead spiders separately not together.

I have crafted 4 tubs of leather armour daily. during the process I have enchanted +50% durability , I have enchanted mana regen, poison resist and several others.
First the armour with out enchantments lasts very short term. second the armour with enchantments other than durability have lasted the same. The armour with durability lasted less and went to yellow and red faster than the non enchanted armour. My thought is that the enchantment may simply be reversed accidentally and it is not giving durability but allowing 50% less durability or 2X damage to durability.
