I'd like to add in case it's useful, that I have a server running Ketting 1.20.1 0.2.18 with all the Mekanism mods and it starts fine.

You just do it, it's easy, about as easy as making a proper github issue.

Check the Get It button for that version on the Ketting Downloads page.

After looking into the logs, I can confirm that this is NOT an issue with mekanism, but rather a mod called Achievement Optimizer, please remove all optimization mods from the server, as most hybrids will not work correctly with them installed
