Signs will no longer display as unknown objects!
This fix has been a long time coming, but it’s now been tested enough to confirm it works.
Some signs placed before the update will no longer display text, but the text is still there. To update them, right-click on the sign, then click Write. There is no need to enter the text again or to change it.
To fix posters, do the same thing. However, if the text displays incorrectly, you’ll need an admin to fix these for you, or if it’s short, you can just replace the poster.

Click inside the red box on “Write” to fix a sign.
