I can spawn one, but every subsequent one I try spawning results in:

"entities/gmod_wire_hudindicator/init.lua:160: bad argument #1 to 'String' (string expected, got nil)
Error - Starting new message without ending the old one!
entities/gmod_wire_hudindicator/cl_init.lua:167: bad argument #1 to 'GetTextSize' (string expected, got nil)"

this even happens if I delete the original one....
