On my server several players have crashed the server when adding a Create Deployer. In local testing if we remove Immersive Engineering it is fine.

We are not sure if this is a Create issue or an Immersive Engineering issue, so it is being posted on both. Creators-of-Create/Create#980

Thank you,

Duplicate of #4604, this is an issue on our side (caused by bad documentation on Forge's side).
