Research ships and maps crash/hang

I’ve tried adding some Kushan research ships to a map, but they cause the game to hang. What is the best way to handle them to prevent the crashes?

Some of my friends have had Kushan related crashes. Try reducing your texture size limit and see if that fixes the issue for you. In my friend’s case it was that they had a 1gb VRAM card and had to set texture limit to 2048. It may not be the case for you but hey… My 2 cents. Plus i’ve been told Kushan are resource hogs.
