  puregym_gb spider broken
  It looks like the PureGym spider (puregym_gb.py) is broken. For the last few weeks it was consistently returning 303 results, but then on 2024-05-04 the number dropped to 1. Looking at the Spider stats, I think it's found 401 branches, but then dropped all but one of them for having duplicate refs.
  
  If I've understood what's going on correctly, the spider code is obtaining a ref from a "gymId" parameter on each individual branch page. However, I don't think this parameter exists any more on those pages. Hence each branch gets the same null ref value, and then all the duplicates are dropped.
  
  Hopefully removing the custom ref code will fix the spider. I think there should be around 400 branches in total. (There's currently 399 unique https://www.puregym.com/gyms/*/ URLs in the sitemap.) So probably even the 303 results being returned consistently before was as a result of incorrectly dropping ~100 gyms.
  
  I've just checked a sample of 15 of the URLs from the sitemap. I found one "temporarily closed" https://www.puregym.com/gyms/tonbridge/ and one "coming soon" https://www.puregym.com/gyms/washington/ . I don't know if it's worth trying to catch these cases or not.
