left_click_mine doesn't seem to work properly

[nebula161]

Reopening since I reproduced the issue.

It seems to fully break a block then get cancelled at the last second. Sometimes, it'll finish mining the block after multiple "attempts", but harder blocks seem to take way longer to have this glitch resolve itself in this way (so sandstone is less buggy then stone which is less buggy than obsidian).

You should be able to reproduce with a simple strip mining bot that places torches every X blocks. (Can't provide the code in this video, it's for a proprietary bot)
Example:
No anticheat's involved, this is a LAN server

I think it's related to item switching (like when you restart mining progress when you switch from a pick to a shovel)

I seem to have been off the mark
