it should, do you get any errors

You mean it should end after a month? Ill ceck the console. The Sargophacus was roofed at beginning and then burned and was destroyed, so I had to rebuild it 2 times its probaly coming from there.

I cant find any errors by clikcing on the Sarg. or Core or just checking.

As said I would higly suggest that it burning and being destroyed one time make it not work anymore.

But when you say it should end after like 1-2 months I can end the event with debug without feeling bad about it.

Replace stuff and me accidently building a reactor core over the molten core could also have caused the problem.
Either it burning and being destroyed or me building something over it other then the Sarg. with "Replace Stuff" could be the problem.

Aight I made a test run where I burned the Sarg. Roofed it, build over it etc and didnt get a single error tho. So I cant deliver on that site.
Still thanks for the fast answer now I can finally end my suffering on the map with Debug Mode.

It keeps resetting the meltdown fallout everytime I end it in Dev mode but ti doesnt throw a error. I guess destroying the molten Core with Dev mode is the only thing left I can do.

is there any radioactive slag on your map

Yes much of it. You think the radioactive slug causes fallout? When deleting the molten Core and deleting the event again it doest reappear
