I made multiple sub-races for a homebrew race and it caused and error. When i backed out of the editor, i receive a new error when attempting to open that sub-race. I am trying to delete 3/4 of the duplicated sub-races. Please assist.

Same issue here. Accidentally created a subrace and backed out without saving. Now it won't allow me to delete.
