i placed my growth chambers & inscribers, went away for some time, as soon as i returned all the growth chambers & inscribers were dropped on the ground and their contends vanished. Happens everytime.

Pack FTB Beyond v 1.5.1

seems like server restart fixed it. But happened again after a while ...

Looks like the same bug as #131. I'm looking into it, but haven't managed to figure out why it's happening yet. Please follow that bug for more info.
