Bukkit

I could not find out yet why and when this is happening, but somehow we got random blacksmiths with vanilla offers although we did not set those prices. We've set for example pickaxeDiamond to [358, 422] which should be calculated to 40 emerald blocks but some random villagers ask for 1-2 emeralds per pickaxe. Continuing to buy the pickaxes generating a new offer works fine again, so he seems to be "controlled" by the plugin still.

We found out some more interesting things about this bug.

In fact it does not seem to be vanilla offer related but instead those are offers of some shopkeeper!

In our case the shopkeepers and the "free" villagers are living together in some small trading world. It seems that sometimes (when chunks get reloaded?!) a (re-)spawned balanced-villager gets offers of the shopkeeper at this position?! Then he walks around as normal villager, still showing the shopkeeper offers. If you then trade with him he generates the correct rebalanced offers loosing the wrong ones.

I'm not quite sure which plugin (shopkeepers or this one) is generating the issue and still look into it too. But I hope you guys get a clue where this could come from with those new informations.

This is happening to me as well, and I don't have shopkeepers.

Changing Assigned status as I'm no longer working directly on this plugin (I actually didn't even see this ticket - I guess there's no notification for them).

This sounds like a strange issue; I know Shopkeepers tracks its own villagers in a separate file. I think Shopkeepers villagers are supposed to unload before the chunk unloads or server shuts down, else they become ordinary villagers added to the main world save. At this point, they're no longer shopkeepers, and would become BalancedVillagers, meanwhile the original Shopkeepers which spawned them would be reloaded as normal.

Have you noticed any odd increases in villager population? Has your server crashed while any Shopkeepers chunks were loaded? Or otherwise, any accidental cases of shutting the server without using /stop?
