It's not a glitch, more of a temporary solution. SpaceEngine sees Apollo LEMs placed on lunar surface as satellites, as they are, for the program, "orbiting" at surface level.
I'm going to ask you to use existing threads for general questions regarding SpaceEngine 0.990, instead of opening multiple threads for each question you have, they'll very likely going to be 2-posts long threads. We will merge such threads in relevant existing topics to avoid such proliferation, as per Forum Rules
. You can find questions threads linked in the above forum rules page.
