Description

Basically, whenever I place a sign from the one of the mods listed above, the console registers an error and the sign becomes unusable.
The sign initially is placed like any other, but it quickly disappears to then appear again, no letting you write anything on it.
NOTE: I am using the Arclight listed above but with the forge 47.3.0. However, I don't think that's the problem here.

Step to reproduce

1. Install arclight-forge-1.20.1-1.0.5
2. Change the forge version to the 47.3.0
3. Install any of the listed mods
4. Place a sign in your server
