When this happens FPS down. The problem in the addons?

I have miracle grow running in background all day, I have NEVER seen that problem

i get it sometimes when im cultivating too, dont know why its happening... i usually just relog and its fine again

Looks like the same issue: https://github.com/WarEmu/WarBugs/issues/1548

It is tied to auto rarity/type sorting in bags options if I remember correctly.

Long term solution is to simply not use em at all for now.

Short term is to move the "jumping" items to your main pack.

Automatic sorting was not working properly last time i checked anyway, so I keep mine off and manually sort the bag contents. Haven't got the problem in months now.
