I hit the wall on this one.
Decided to mod starting units in OSH. Faaar too much junk on the map. Is there any limit of what engine can handle numbers-wise?
I removed overwhelming amount of rubbish (fighters, transports, corvettes, frigates) although ignored Pirates. Added some fun ships here an there. Defo not as many as removed ones - just some capitals/cruisers here and there - Eclipse over Byss (yay), some MCs/Bulwarks for Rebels to give them more punch overall.
Problem is: if I modify only Byss (added Eclipse, removed junk, changed number/class/version of ships in orbit) everything is fine. When I proceed on a galactic scale OSH always hangs, ctrlaltdel -> kill process. Make no mistake, number of units removed is higher than added ones.
Really puzzled by this. 
And modding planet by planet, load/quit, mod/load/quit.... testing if scenario is still working - not fun at all.
