I've been creating a bunch of homebrew subclasses for blood hunter, and using the homebrew template function to help me lay out all of them, as well as to find examples of stuff in other subclasses. Up until this point, it has all been working just fine. However, a few hours ago I encountered a problem. When I went to look at the template for the College of Creation Bard I discovered that none of the subclasses were showing up as templates and, in fact, the entire "select a subclass as a template" section was greyed out and not available. Has this happened to anyone else? Have I hit some sort of limit with how many I can do? Does anyone know how I can fix this?

Nope, I just checked and could not replicate that. I selected bard and Creation was top of the list as anticipated.

Yeah it's still exactly the same for me, nothing's changed
