Oh i forgot on thing I did get done between roll backs and server crashes was swap out my open block tanks for Rail craft ones.
Any reason for that from a crash\issue perspective? (other than the visual glitch you had in one of your vids, I have noticed that the openblocks tanks are a fairly heavy load on the server via Opis. But not quite as heavy as a "stuffed" TC4 alchemical furnace)
I'm asking since my current pack doesn't include RC so all tanks in my world are Openblocks ones, and I have a lot of tanks.
