We have a winner!!
I took the base plate off this evening and this is exactly what's happened.
Both the slot and the flange on the end of the pin have worn, allowing the plate to tip over.
Wonder if base plates are available?
If not I'll look into those entire electronic module dizzies.

Thanks for letting everyone know what the issue was. This is the sort of thing that is needed to make this forum a lasting resource for other users in the future.

Indeed!
Thanks for everyone's help.
