How to reproduce

I have a netherite pickaxe to mine with
On a realm with no one else online

once it had to go up to reach the valued block it stopped working and my screen started to lightly shake

Modified settings

assumeStep true
chatControl false

Final checklist

• I know how to properly use check boxes
• I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
• I have included logs, exceptions and / or steps to reproduce the issue.
• I have not used any OwO's or UwU's in this issue.

Have the same issue when using the build command. Works fine until the player jumps, then crashes.

Turn off #assumestep to make it jump.
