I don't know to be honest m8. Heard something about a bell(4) but that's about it. Not sure what you have to do, nudge in the bell(4) whilst on feature board, collect cash then maybe it holds on the bell(4)?!?
Not trail holding for £10?!? Perhaps they're cyclic and go through this phase now and again.
Hope that helps,
Cheers JG
