T1234... I do have Orulex installed but have it deactivated in the modules. So should i remove it completely?
I don't know if I am running the OGLA client - i will check this.
I only work with the DGIV - I don't have a single DG "activated" in my scenery file.
dgatsoulis: your scenario code didn't work either.
But, folks, i managed to get the scenario run.
I did the following.
I entered in the cockpit mode of Arrow freighter. I changed camera and focus to view the PreludeII Base on Europa.
There I changed to exrternal view - and slid the zoom factor a bit backwords, so to make everything look smaller.
Then I changed vessel focus back to Arrowfreighter - and... BINGO! I was able to view the AF from the outside, and thus also the attached DGIV. I was able to move on then in my scenario.
I fear and have now the proof that it has most likely to do with PreludeII Base. The same thing happened on Mars with the Orcus PreludeII.
It seems to be some UMGO error
But thank you to all for your inputs, they were if not directly connected to a success still very helpful to clear all other options.
If anybody has futher details about the PreludeII Station I'd be happy to share them here.
