Played for a good long while in build 3604 and though it did take a few hours, I noticed some slowdown that ended in a crash. Which sucked because I had done like 30+ days and got a ton of progress made. Wiped it and started a new world, ain’t got time for that.
I don’t have any definitive proof that there is a memory leak but it smelled a lot like one. Might be worth looking into.
