I have already mentioned this on Steam, but I will report here aswell.
When it comes to the snapping bug, there is sort of a workaround. An annoying one and not perfect, but still a kind of workaround. Go to any location nearby where you build and make sure the blueprint is un-snapped. Rotate the thing you want to place into the proper rotation, then go and place the item. If it isn't correct, repeat and rotate the amount that is wrong (on pc, use Q and E, not mousewheel) and do so until it is close enough. If you get it perfect, good foor you. :)
Explanation: Seemes the game remembers the world rotation you have on the item, so as soon as you place a blueprint it autorotates the blueprint when you place it on a snapping item .
Atleast this seemes to work for me.
