That's something that has happened to me before and in my opinion it depends on just how much it effects your booking plans.
For example, if it's something that doesn't play a massive role in your plans and it can be easily changed to something else then I probably would
scrap it and come up with another idea. However, if it were something I'd had planned for a long time or it had a real impact on my booking moving forward, a key element so to speak, then I would carry on as usual with it despite it having been done. Can't be helped that our great BTB minds are shared by those in WWE creative right?
