Pumpkin Galeux d'eysines Fruit Rot

Hello. This is my 1st pumpkin grow using grow bags on the garage roof. If has been battered by the weather, but grown well so far. Noticed a small patch of colour change on my pumpkin, but now as seen in the photo is has become rotted holes! Is it about to rot away on me? Should I harvest it?

Any advice would be very appreicated.

 

No expert but it looks ripe to me.

 

I was wondering that. Thanks. There are some more forming so maybe removing that one will help the others? Going to be very windy tonight and tomorrow so I'll leave it on vine as a weight. Unless I get an overwhelming response saying cut it!
