It is possible that this may affect 1.16.4, but I was playing in the newest snapshot (20w46a) when I noticed that my composters where suddenly disappearing. What's strange is that it doesn't affect any other "appliances" (crafting bench, anvil, stonecutter, chest, etc.) ONLY the composter. Also, a random block was set on fire when I turned randomTickSpeed to 1000, though I haven't been able to replicate this bug. It was near lava, but it wasn't an adjacent block, and it was cobblestone which is fireproof. I have made four composters now. Please help.
