Shopkeepers version: 2.2.2

Spigot version: 1.11.2

Hello, I created a shop with the shape of a Magma Cub but he himself grew up and then become a child. How stabilized at a certain age?

I think the magma cube (and any other mob) might currently randomly spawn as either child or adult whenever it gets respawned. There is no way currently to persist or edit whether the mob is a child or adult.

Before support for something like this could be added I will first have to separate the mob properties into a separate inventory menu (see #10, which already mentions child variants of mobs as feature, so I will close this as duplicate).

Alternatively you could probably also use the integration with citizens and spawn a child citizens npc and use that as shopkeeper. See the wiki on the Citizens integration.

For the time being (until proper support for selecting and persisting the baby-state of mobs has been added) I set all spawned mobs to adult now, so that it at least dosn't randomly spawn baby variants anymore.

ok thank you, suddenly you will make an update for the mob keeps his adult size by default?

This will be part of the next update. No ETA on that yet though.

ok, I look forward to it;) thank you
