Hey there @gideon77 
Since DSA5 Kampagne - Das Geheimnis des Drachenritters | Foundry Virtual Tabletop is a Foundry premium module, it’s unfortunately difficult to check for any errors by attempting to replicate the issue on my side.
I’d like to ask you to please check two things which will hopefully give us more information on what might be going wrong:
- If you open the dev tools console (F12) before importing, do you see any error messages logged there?
- If you install the module on a Foundry instance running on your local machine (with the same Foundry version), does it behave the same way?
If yes to the latter, then it might be something that would need to be brought up with the module developers’ support.
Checking the above will help us to figure out where the issue is coming in!
And if it works on your local Foundry instance, you can also use the Import Wizard to import the world to Forge (see: Importing a custom module using import wizard)
Hope that helps! Please let me know if you see an error in the console.
