When landing on luna (most likely also other planets) the craft reorientates itself all the time to get the command chip facing up.
Landing it in normal locked mode is possible though
step 1: pause ! (The lander is already in the right position)
step 2: switch to retrograde
step 3 try to land
slider 1 is landing gear
I don't know, if that behaviour is intended, to make landing with normal crafts easier, but that way the only way is to constantly reorient the lander
The newest version should have improved how this works. As long as the command chip/pod is facing up relative to how you want your sub craft to orient upwards, then it should work.
