Vault Chest Mining Fix

Vault chests and Living Ornate Gilded Coin Piles in the Vault Hunters modpack can sometimes break slowly even when the player is standing on solid ground. The cause is a mining speed penalty that the game normally applies while the player is flying, swimming, falling or stepping off a block, including slabs. In the affected case that penalty is not reset after the first break, so each slice of the chest comes out at the reduced speed. The mod ignores those subsequent checks for vault chests, so the penalty no longer carries over into the rest of the mining.

The fix is limited to the mining speed penalty and to vault chests. Wooden chests and strongboxes are also named by the author as affected by the same bug, but the penalty is only negated for the chests the author targets. Other blocks keep the normal game behavior, and a character still gets the usual slowdown when blocks are broken too quickly while airborne.

The mod is for Forge 1.18.2 and runs on client and server, so it must be installed on both sides. Its author states it is required on clients and servers, and servers can still prevent vanilla clients from joining. The code is released under the MIT License and is not open source.
