I am using pumps in the Nether to pump lava for generators. However I keep having a problem where the pumps stop working. They have plenty of lava surrounding them and the pump in facing the correct direction. When I am looking at the pump it appears to pump once ever few mins. Sometimes if I turn the pump to a new direction it will work for a short time. Same thing If place a new pump in the area. Seems like there is a bug somewhere. My version is 1.10.2, IC2 version industrialcraft-2-2.6.252-ex110, any help would be appreciated.
