In shop search, when I try to go to a legacy shop I am redirected to the "Your Shops" page. This happens if I click on the name of the shop directly from the search, or if I've bought the item and click "continue to shop."

I'm having the same issue, didn't realise it was related to legacy shops though. As far as I remember staff added legacy shops to the search just for questing purposes, so I guess not being able to get to the shop itself makes sense in that regard, but it would still be good to be able to mass buy stuff for the recycle beast etc if possible.
