i'll think i found the problem.
I deleted RO (RealismOverhaul), because when i have dont the loadning screen freeze at MIR_core or MIR_RCS truster block.
How can i fix this? And should RealismOverhaul give me the BIG solar panels of the iss? Or can i deploy radiators?
And i have watched under structuals but cant find the Big solar panels of the iss. Only soyuz and MIR solar panels which are under Utility.
