Getting this error on startup, suspect it's related to shopkeepers

Hm, I currently doubt that this is related to shopkeepers:

The error seems to occur when it tries to save the trades of an villager entity for a chunk which is currently saved, however:

Shopkeepers doesn't actually modify the trades of villagers in the world (only their behavior to stop them from walking around). Whenever a player trades with a shopkeeper a new villager gets temporary, internally created, the trades for that internal villager get modified and then opened for the player. However, that internal villager entity is never actually 'added to the world', so it shouldn't be saved together with the chunk either (the chunk doesn't know about that internal villager entity).
If you disable/remove the shopkeepers plugin from the server, does that error still come up?
Could it be that you have modified or created a villager by any other means, maybe via some other plugin, or by spawning a villager with custom trades via minecraft's commands?

Can't test that easily :/

Doubt it, don't remember spawning any.
If only I knew what world to look in.

How comes that? This seems like the easiest and quickest way to me for verifying if shopkeepers is related to this.

Maybe your world management plugin allows (un)loading worlds on the fly. So depending on the amount of worlds you have you might maybe be able to trigger this error by unloading and reloading one world after the other. (might be laggy though)
Besides of that, I currently don't know how I could help you further here.. Never had this kind of problem yet.

Many players online, anyway I disabled shopkeepers and it still happened. So probably not this plugin.
Closing this, thanks for help!
