color codes are not working on the sighs on the last update of the mod. It was working fine before.

I have the same issue.

Good that it's been noticed by luacs :)

This has been solved with the most recent update 1182.

I'd like to add that it's only been somewhat solved - if you edit a sign, the colour codes don't apply properly.

But then again editing has always been shaky so it's not a high priority.
