Linux Dedicated Server Cook Error

Hello,

Building linux dedicated with following command:

RunUAT.sh BuildCookRun -project=/home/gs/Game/TechCompliant.uproject -noP4 -platform=Linux -clientconfig=Shipping -serverc onfig=Shipping -cook -server -serverplatform=Linux -noclient -build -stage -pak -archive -archivedirectory=/home/gs//Server/

Results in a stack trace error as the Editor is invoked I believe to cook content?

UE4Editor: Fatal error!

Now clearly this is a error in the Dungeon plugin but question is why is a Editor only module (“Type” : “Editor”) being brought up in order to cook data?

The error appears to happen due to the plugin declaring the thumbnail generator outside of the class any pointers are appreciated.
