Not sure what caused this specifically, but whenever I try to go through a nether portal within a few chunks of a Deployer, the game hangs. I tried breaking the deployer, but this didn't change anything and the logs still show a DeployerTileEntity as the source of the error. Moving away so that the chunk with the deployer is unloaded allows me to go through a portal, but then I get similar errors, like being able to break the nether portal frame and the portal blocks not breaking with it. To be clear, the game doesn't fully crash, it just gets frozen.

The deployer had a hopper with saplings in it pointing towards it, and was attempting to place saplings.

Here's the log for just the error:

This issue has been addressed in 0.2.3. Thanks for the report and feel free to re-open if need be.

I'm still having the same issue after the update, but there is nothing in the log to suggest that Create is still responsible, so for now I won't re-open.
