Additional information: The Problem with the Filler is the Follow when the Filler started normaly, then one time it´s stops and the filler Battery is in the Minus Area . I think that is an Bug.

Edit: I use the mod on a Server.

Can you describe the problem with more details and screenshot?

The Fillerbattery goes after few Minutes in the Minusarea then i must restart the server and then the Battery charging up and then after a few minutes the battery goes in the minusarea back this is also in the version 1.12 you can see it on the screenshot
