Something very strange is happening with redstone torches lately. Normally, a torch would turn off when the block it’s attached to receives a redstone signal. It still does this, but only to  an extent. It’ll work, until you leave and reload into the world. After that, for some reason, it’ll only turn off when the signal strength that the torch is receiving is at it highest possible strength, 15. Any lower, and the torch will stay on. What’s weirder is that once you change anything to the circuit, like breaking and re-placing a redstone dust or torch, it’ll work again. What’s even WEIRDER is that when I discovered this issue, another NOT gate right next to the one that was having this issue was working just fine. I think it might have to do with direction? The buggy NOT gate had the torch facing east, with the normal working one facing west.
