I don't know if it's a bug or some incompatibility with other mods. Also, they don't have a hitbox, so it's necessary to break the supporting block to collect the sign and readjust its position.
The mods I believe are related to this problem are:
- Handcrafted
- Lucky's Cozy Home: Refurnished
- Lucky's Palette
- Lucky's Showcase
- Spud's Shops
- Via Romana: Infrastructure-Driven Fast Travel (the main suspect for a possible conflict, as it modifies the sign system for teleportation)
However, the regular signs in the game don't have this problem, so it could also be a bug.
