I imagine it's a multi-faith chapel and that specific goddess is having problems?
The bigger plot hole is why the adventurer bracelet, despite having fast travel and other convenient (potentially revolutionary) features, fell out of style. Falling out of style implies old lady had a thriving business at some point, so why wouldn't this miracle technology spread? And I doubt we'll ever get an explanation (especially of how fast travel works, like can you just register any old town gate? That's kind of a weak magic system IMO, but I bet they hand wave it all away regardless because "MMO lmao")
