Server error: deleting palettes

This has bugged me since Christmas...

I have positions that I would LOVE to get rid of from a Christmas show. However, every time I try to delete certain palettes it gives me a different delete message: "deleting used palettes will replace references with hard values...etc" Insted of just "are you sure you wish to delete?"

Then, as I try to continue from there, I get an error saying "server busy, please try again (in 5 months so i'll say the same thing) (object 24 in array 23)

So, is this operator error, or a bug, or something in setup? Or what?
Help would be much appreciated.

I am running a Road Hog v3.1.1

Thanks
