An area that was very normal and TPS was fine in, not too much going on, even with Create stuff happening underneath, has suddenly had its TPS start to have issues. Looking around with a mod that shows how much TPS block and entities are using, I didn't see any huge offends, and even after trying to fix them, I'm still not seeing an improvement. But, if I'm in spectator mode, the TPS immediately returns to normal. I'm not sure what the issue is, is there anything I can try?
