Signs & Decals 1.3.1: signs no longer vanish behind cladding
If you hung a sign on a frame and built composite cladding over it afterwards, the sign was gone. From 1.3.1 it moves in front of the panel by itself.

A player reported that a sign is no longer visible once a covering is applied. This is the composite cladding from the Kit (Cladding) – some game languages call it "covering". The sign was then hidden inside the 13 cm thick panel.
The cause: signs keep measuring where the visible face of a wall, floor or ceiling is and place themselves just in front of it. In the game, however, composite cladding is not a wall and is not released for mounting, so the measurement skipped it.
- From 1.3.1 cladding counts like a wall. When it is built, the sign moves in front of the panel right away; when it is removed, it moves back – for wall signs, data signs, decals and light signs on walls, floors and ceilings. Flush mounting works in cladding too.
- Existing signs behind cladding correct themselves when the save is loaded.
- Note: the game does not allow mounting anything directly onto cladding. Hang signs on the frame or wall first and add the cladding afterwards.
