Recurrent Complex is a mod which allows for pre-generated structures. I was using it to replace vanilla torches with realistic ones instead. However, I found that their rotation was consistently placed wrong in my tests.

After some back and forth with the Recurrent Complex developer, I found that only Realistic Torches were affected, and vanilla torches were not.

(Realistic: Left, Vanilla: Right)

So it seems that Realistic torches are not respecting their rotation under certain circumstances.

This is likely an edge case, but a fix would allow me to replace all vanilla torches in structures with realistic ones to avoid making them too easy to get.
