I have providers on my (forestry) fermenters, pulling out liquid to go into my stills. Strangely, my provider/supplier liquid setup keeps breaking for no apparent reason. Occasionally, especially just after login, the liquid will get transferred. Then it reverts to not working again.
I didn't have this issue early on, even though it was the same version and the same configuration of pipes.

I'm using FTB unleashed 1.1.3. I've tried the modpack Log Pipes version (LogisticsPipes-MC1.5.2-0.7.3.ftb.631) and LogisticsPipes-MC1.5.2-0.7.3.dev.666. The issue seems to be present in both. Would much appreciate any advice.
