error killer
by sigmapowazna
Error Killer is a Fabric client-side utility for block placement that handles obstacles in the way of a placed block.
What it does
When a block placement is blocked by an obstacle, Error Killer clears the way so the block can still be placed. The author describes it as a way of placing a block when a lever or button is in the way, with Water Bucket and Lava Bucket taken from the hotbar to clear space. The mod runs on the client alone, so servers need nothing installed. It is published for Fabric only, for 1.21.4, under the MIT License, and the code is not open source.
