Minecraft froze and crashed when rapidly breaking blocks and/or flashing through pause menu with rapid click macro, 1400 clicks/min. I used Autohotkey to simulate the mouse clicks.
Game freezes as if no blocks have been brocken, when reentering world they have.
To recreate:
Create a Singleplayer world
look down
use macro to rapid break blocks
Cannot occur in normal play, no one can mangage to click the mouse with 24 Hz.
Therefore resolved as invalid.
If you create a procedure to recreate that issue without use of 3rd party tools, please provide this here.
