That sounds like the scenario was not properly setup.
What's the starting system name? Do you see a sector called Crown?

yes crown is here. Ellyon is the start system name.

there isnt a UCH ship either

"Ellyon is the start system name." - this doesn't sound like RE.

In RE you would start on Alpha or Beta as the starter system.

I'd suggest removing RE scenario. Closing Empyrion and Steam completely. Restarting your computer, re-add the scenario via the Steam workshop.. Then start a fresh game / save . (Single Player or Multiplayer RE)

Even in War and Industry?

Try that advice. That's the default vanilla starting system so something went wrong when setting up the server.

unfortunately we already have players playing for almost 3 weeks on the server so we'll have to wait for the upcoming update or season 2 to wipe the server and reinstall it... :(

another question, stars indicate the type but not the advanced one, exemple G/N/F but not G1 G2 ect. is it an issue linked with the fact that RE wasnt properly installed?

At this point any issues you encounter you can assume are because of this.\
Sounds like you're playing the vanilla game world with RE missions. It's not going to be an enjoyable experience for anyone.
Maybe you can have players blueprint their stuff and then do something to give them a head start on a fresh RE save or something. But you'll just encounter more and more problems the longer people play using this very broken save game.

I understand. Thank you for your answer! I will see what we can do

Yeah Clad Strife you could do a wipe and give the players a head start on the new play through to make up for losing 3 weeks of progress.

Let everyone know. Set a date a week or so out. Then have a server Admin give everyone who is playing on the server currently the following resources on re-launch:

90k Copper, Iron, Silicon ingots
100k Carbon Composite
50k Cobalt and Neodymium Ingots
30k of Erestrum and Zascosium Ingots
25 Large Optronic Bridges
25 Large Optronic Matrix

They would be able to build almost any Capital (within reason) from the start.

wipe is done and everything is working perfectly ! thank you so much

we dont want them to build a cap on start though, hardcoore server here ^^

they've been very understanding so its all good

Glad it's working out so far!
