The apparatus was a vital part of the upkeep of the facility's nuclear reactor - and you just took it out.
With the facility meltdown mod the appartus has a lot more risk (and reward) attached to it. When you take it out the entire facility spirals into a self destruction sequence! You'll have 2 minutes to escape and take off before you get vaporized.
Take a look at the known isuses if you have a problem, otherwise join the lethal company modding discord and find the FacilityMeltdown thread and report it there!
Only the host needs to change their config as it is synced.
lethalconfig or lethalsettings will let you edit the settings in-game.
There has been previous reports of modded moons not playing well with this mod! As always go over to the lethal company modding discord and I can try and take a look. There seems to be no problem with Lethal Level Loader or LECore so it could be map dependent. In which case I wil NOT be fixing it. I can not fix every modded moon in this mod otherwise I would get nothing done.
