>>For example, if you relog while right next to a trident it will slide down the side of its block. This makes some trident killers that used to be relog-proof now require the tridents to be re-thrown after relogging.
This is similar to what happened in my gold farm w/ quad 2x trident killers (single player). I logged off to do something while it was running, then upon logging back in i noticed none of the zombie pigs were dying. Set to peaceful to troubleshoot and found that all 8 tridents were gone. I had initially thrown them at the center of a 2x2 blocks on the floor though, not the sides of any blocks/pistons.
@GoldenHelmet - will that fix eventually hit 1.17.x as a hotfix or will we need to wait for 1.18 before using trident killers safely?
