A round with user defined transitions that is not...
Ever created a pretty simple round, picking a single edge but it fails for no good reason, and you get the error message:
Recent changes have caused user-defined transition references to be lost. Changes to either the current feature's geometry or to some other feature have caused the references for user-defined transition (No. 1) to be lost. The affected transitions must have their references redefined.
Recommended actions: Redefine the TRANSITIONS element for the failed feature, and select the Transitions indicated above for redefinition. Reselect lost references.
The problem is... there aren't any user defined transitions in my round. But... I can go to the transitions tab and see 1 or more supposedly failed transitions. I can delete them, even though they came from nowhere in the first place, then go back to the sets tabs and tick it off... and of course get the same error message again, as though I had done nothing to delete the transitions, which is fair enough as I never created them in the first place.
I have had this bogus error message come up for several years, well before Creo, maybe before Wildfire, but I'm not sure. Why don't PTC fix things like this instead of messing with menus?
