Good evening, I have successfully installed Cardboard 1.20 as well as ICommon. However, I believe that one of the mods is preventing Cardboard from functioning properly and therefore causing the server to crash upon launch. Here is the latest.log. I hope you can identify the culprit among the list provided in the logs.

Thx !

The mod Smallships is incompatible with cardboard. There is no fix at the moment.
