Some information

Operating system: Windows 10 Pro
Java version: 8
Minecraft version: 1.12.2
Baritone version: github build
Forge mods (if used): None

Exception, error or logs

No errors were printed.

How to reproduce

Place a regular chest and walk 10+ blocks away from it, make sure the path is possible to be made without breaking any blocks (Do it in a superflat world?)
Run #allowBreak false
Run #goto chest (It will say no known locations)

To fix the issue you run #allowBreak true and then #goto chest will work again

Final checklist

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

I can reproduce this with Baritone Fabric 1.6.3 on Minecraft 1.16.5. Java version 16.

This is actually already fixed in 43d5458, which is in the latest release for 1.12.2 (v1.2.15 as of this writing) but not yet ported to newer Minecraft versions.

Were you in the same chunk as the chest?

Well are there any chests that you can physically get to without having to break blocks? Works just fine for me
