Colored Signs Wall Glitch

IGN: martinq17
Date/Time: Same day that they added the perk
Glitch: Signs on certain walls/blocks cannot show colors.
Steps to Reproduce: For example -- On logs, you cannot place a sign, write in the code for the color, and then see the color once it finishes. If you write the same exact thing on a a sign on the ground, it works perfectly.
Evidence: Place a sign anywhere and you can see what happens.

 

It works for me on logs.

 

Starting working again. You just have to be at quite an angle from the sign. Go ahead and lock this plz

 

Sure
