Hi there,
While it’s certainly possible, I’m not entirely convinced this is a bug and I can see valid reasons for keeping the other vendors at level 30+
You could definitely argue the other way as well though, and it’s certainly valid feedback in any case and might benefit from a wider discussion. Which is also why your thread wasn’t removed, Ultimutt, but rather moved to GD and is still available there.
Feel free to continue the discussion there, or as always if you believe something isn’t working as intended, report it as a bug.
