[Crash] Stable precursor build (only when going towards precursor island)

OfficialRandomGaming

So my issue is this, whenever i'm heading towards the precursor gun island, or heading anywhere east, my game will start to freeze frame, i'll go easily from 60+ fps to single digits, occasionally it'll render for a few more minutes with jumping frames here and there, but most of the time before i can even get into the mushroom forest, the game will crash.
