Before Patch 3.0 or Legacy of the Void, I've managed to create a custom unit successfully with portraits, weapons, models used and everything it requires, but now, I can't create them because a created custom stuff DOES NOT appear on any list, but it's still there in the Data Editor. Ex: Creating a custom unit does not appear in the unit selection in the Editor.
I'm also having a custom Selendis and Urun Champion for the Twilight Council by creating requirements (that only makes them to only have 1 of them in the field) that those default champions have. I did it with success, now I have to go to Twilight Council and edit the Champion ability by adding them, and their requirements so there can only be 1 of them in the field (if they die, the buttons become available again). However, the requirements I created do not appear in the selection (keep searching, but I failed)? Any solution?
