All clients who join a game with https://steamcommunity.com/sharedfil...?id=1600215240 get an error saying "Error Building XML UI on Block Square - : a name did not start with a legal character 45 (-) Line 6, position 110."

Once the client is promoted, they see a giant white UI box around the object. Non-promoted clients don't see this white box.

All the UI is fully functional for the host, but not promoted clients. The host never gets an error.

Code for UI XML:
