That's because there's the weirdest bug with shell 202. For some reason it exports fine, but when I link in the Age Uru deletes the PRP during startup (like it sometimes does with corrupted PRPs) and then rightfully complains that it is missing. That bug is older than the hills but I was never able to found what caused it. So to work around that I added the shell 202 to the core city PRP a long time ago, and I just never looked at it again. Until now that caused no problems, but Robert's paging system might be confused with that missing PRP.. ( ) I'll have a shot at it again and see if all the PyPRP fixes over the last months have somehow fixed this.
This bug is just weird *shrugs*
