I assume it's some kind of a severe memory leak?
It happens after I played on my world for quite a bit, then without prior warning or suspicious signs/behaviour, it starts to lag severely, will last even outside of mc, affecting my entire PC performance, right until I restart my pc.
It happens recently. Not sure how to investigate, using spark doesn't seem to detect anything too out of the ordinary.
Im playing on 1.20.1 forge. Forge version 47.4.8.
Will give out latest logs or spark report or modpack or whatever if u guys need it.
