Hello, first time using IC2.
I ran into an issue with a vanilla hopper crashing the game when placing it by a rare earth extractor and filling it with dirt.

The error log said something about ticking block entity for the rare earth extractor, here is the crash log.

Will do, thank you!

This looks like a canary issue.
please use Radium or Rubidium (which one is the lithium port)
Or report it with canery.
We tested with Radium/Rubidium and there is 0 issues.
