Describe the bug
The chemical bath multiblock will crash the server with a java.lang.NullPointerException: Ticking block entity. Something else to note is a user cannot connect EE pipes or Thermal Foundation fluiducts to the chemical bath and pump liquids in. The pipes simply do not connect to the machine.

To Reproduce
Manually insert a bucket of etching acid into the input port in the chem bath GUI
