If you know about such a module that should not be flipped or will cause issues if flipped, please let me know.

I see the devs explicitly prevented flipping all buildings that fit into a slot(settlement, cargo dock modules, etc) even though all that I saw are perfectly "flippable".

I have 2 hypothesis why so:

1. Flip also triggers a rotation in the game. And slot modules aren't supposed to rotate. Both their position and rotation should be strictly aligned with the slot. I had to fix rotation for the flipped modules, but that was a pretty easy solution.
2. If there are some modules that due to their geometry or function should not be flipped, devs could simply block it for all slot modules as an easy fix.

Considering #2 is possible I limited the mod only to settlement modules since they all fit the purpose.

But it would be great to know if I could make it universal or not.

The building is nicely mirrored. But there is a problem, because a mirrored building shows that it has water, but water does not flow into it and wastewater does not drain away.

That's weird. Thanks for reporting, I'll check it

I've released a fix for it in v0.1.1
Please check it out.

It works, but I had to tear down the mirrored structure and rebuild it. Now it works as it should.

Good job.
