I am running the newest version of Mekanism and all its co-mods. And i am having trouble with all the pipes, pressure/mechanical ect. They jsut randomly quit working and i have to remove them all and place them back down to get them running. They are going to and from mechanism machines.
My Version Number for Mekanism is 8.1.5.246

Yeah, this is the same issue. Merging with #2806

This is possibly the same as #2806. I am also experiencing this. Network reader shows part of the line of cables/tube as "No Network". Replacing just the junction of Network/No-Network does not fix it. Instead you have to remove the entire No-Network section and replace it. Exists with power, transporter, and gas tubes.

As a temporary solution, and to handle any future problems, it would be nice to have a console command that reinitialize/redefine/rebuild all Mekanism networks. Probaby an OP only command.
