I see that all 232 entries for The Robin 2 have been changed to The Robin and it's as if there was never a venue called The Robin 2.
Surely the correct action would have been to mark The Robin 2 venue as Closed and create a new venue for The Robin. There are plenty of precedents for this (e.g. in the UK, Academies which became Carling Academies and then O2 Academies).

The next step would be to identify when the name change occurred and ensure as best as possible that gig entries are placed under the correct venue name i.e. the name of the venue at the time the gig took place.
A quick look at Google Streetview puts the change somewhere between August 2018 and May 2019. So currently there are 5 gigs which fall into the gray area between those 2 dates but 188 which should still be listed as The Robin 2 and 39 listed as The Robin.

I'm happy to put a note in the venue biographies if the changes are made.
