If you are holding jump as a boat breaks on a cactus (or press jump just as it breaks) then you'll start to get glitch behaviour, most noticeably.

1. Blocks don't break on the first attempt, especially noticeable with eff 5 and insta mine, netherack for example can take multiple attempts to break. The behaviour almost mimics ghost blocks except nothing in the logs to indicate that issue.

2. Firing arrows, arrows fire even more randomly than usual, either falling very short of where you're aiming or massively going past the point you're aiming at.

I've uploaded a video of both behaviours - https://youtu.be/EErbhOFwBzI can also upload to onedrive if required. I've attached a screenshot of how we configure our ice roads and a sample world but it's replicable in any world single and multiplayer so not lag.

I believe the game still thinks the player is in a boat but I can't really see anything in the logs to prove that. It only happens when jumping, if you let the boat break then give it a moment before moving the issue doesn't happen.
