My Type Mark parameter for a standard generic model family doesn't allow me to have anything besides a number. I have probably 30 other generic model families in this project that have tags with letters and other characters, and I just started getting this thing where I can't tag any new generic model families because this parameter won't work.
I can't find any way to fix this.
After 3 1/2 years working in Revit, this is a heavy favorite for the "stupidest thing I've ever seen Revit do" award.
