Fluid pipes looks unconnected between chunks when restarting server/world.
Pipes works as they should, but it does not look good...

Tested with Forge 14.23.5.2846 and just IE 1.12-92

Subscribe, same effect and version. The log does not show anything suspicious in that matter.

I can't get the 1.12 project to build, but made some experiments to provide some more data:

• The locations are very repeatable, but not 100%, rarely it renders correctly.
• The missing pipe pieces appear only to be in x+ or z+ direction (as shown in the screen shot).
• Does not happen when resource reloading, only on quit->reload.
