#1 Original report

As the title says, all blocks are rotatable since a while ago but I never had the motivation to bug report it. Most of these are only visible with normal maps on (like hull).
Some blocks like the build block/crystals/grills/lights/... have orientated textures and you can see the rotations. I rotate them with the mousewheel since the orientation is not available. As far as I know, it happens with every block in the game.
2 screenshot examples included.

I believe this to be a feature, such that blocks with directional textures can be orientated in a way of our liking. Maybe the issue should be changed to "Game incorrectly rotates normal maps".

If it is a feature then the preview should be visible. You can only rotate it with the keyboard keys or your mousewheel. You couldn't do this a while ago, some update made them all rotatable so I'm not thinking this is a feature.

still a thing - increasing priority to normal
-> causing a visible effect without giving an explanation to the player
