Infusion Durability patch 3
Infusion 2 claims to be compatible with quality and durability, but for me every time I reload, items' hit points get capped at 100. (I just realized that Im playing on 1.4, so maybe it is actually patched in 1.5. Huh. Whatever though, if you have the same issue feel free to try this mod) .
This mod was made for Infusion 2 & QualityExpanded, but it might work with similiar mods.
The way it works is, I think Infusion calls MaxHitPoints getter before the game gets a chance to read from save files what quality the item is, so I just set the quality to be Legendary for that time window. No idea what problems it might lead to, but I dindnt encounter any. It might work completely fine, might break your save.
Should be safe to remove mid game.
