It is your problem that the stadiums have been deleted. I am starting to get very annoyed with a lot of you now. I make it very clear if you install this mod, you have a chance of losing anything you have added. Even if I am not clear enough, this is very basic stuff. Also, I have no responsibility for any modifications any of you make. That is all on you. My responsibility is for the mod. So if I release a mod tomorrow that deletes all stadiums or faces or whatever I want that is up to me.
As for the stadium list, I couldn't be bothered writing them down. I do not have to answer any questions. You're not paying me. Also, I add stadiums as a curiosity. I don't have to add any stadiums if I don't want to. Same for any other graphics.
Yes, the ID's are too high for CM14/15 to read. Don't forget to update the compdata because it won't work now you have changed the ID's.
You're definitely not the only one. The mod is generally very stable, with very minor issues. I'm pretty happy. I've had releases before that just didn't work at all
