The original mod has been fixed:
" Version: 0.11.5
Date: 2026-01-24
Changes:
- Vaults are now assigned to the force which captured their console in situations with multiple player forces "

While playing multiplayer with custom forces, mods that are hard coded to set essencial structures to the force "player" (default single player force) can cause issues and become unplayable not unlocking essencial technologies or making the player unable to set their unlocked recipes to the machines. this mod solves the hard coded part of the Vaults in Rabbasca, this way people playing with multiple forces can still enjoy this awesome mod.

Patch mod: makes Rabbasca hacked vaults (vault crafter + console) belong to the nearest connected player's force instead of defaulting to the 'player' force. Also includes a safe prototype guard for rabbasca-vault-meltdown.minable if needed.
