@L3VELZ3R0 Hi!
The maximum durability was doubled for most equipment, so if you had an item with 100/100 durability it now sits at 100/200. This is why it appears that you've lost durability. Please feel free to submit a ticket if you run into any other issues.

@DjOvery Hi! The durability of most items was doubled, so if you have an item with 100/100 durability it now sits at 100/200. This is why it appears you lost half of the durability.
We are working on a hotfix for the crashing issue regarding the sorting feature with hopes to release early next week. Until then, please refrain from using this feature with a chest full of many items with large stack sizes. Thank you for your understanding and patience.
