Version : 1.21-1.7.2
Loader : Fabric

I could be playing for like a minute or two and then after a bit I break a block and notice it doesn't drop anything, then I look at the mobs and the'yre all standing still. Attempting to save does nothing even with autosave and then when I click "exit world" it softlocks me in the exiting world screen til I kill process and then load the instance up again to see I've been rolled back. Its gotten so bad I can't even get 20 seconds into my world without the game doing this. I've tried my world without legacy4j and its just a legacy4j issue. I have footage of this as well and literally have no idea what could be causing it

(IT STILL DOES THIS EVEN IF IT IS THE ONLY MOD INSTALLED, IT WORKS FINE WITHOUT LEGACY4J)

Make sure autosave is on, and that minecraft has more ram dedicated to it. Hoping this will be fixex next update

tried that, autosave actually DISABLES ITSELF on startup and I have like 10gb of ram allocated so its not that, without the mod installed saving works fine so this is a bug that is actually making playing with the mod impossible

Also in the clip I turn autosave on

I would also like to add that the vines you'd get from the jungle biome are literally invisible in the hotbar, its not that they blend in I mean the texture isn't in the hotbar
