@vemacs shouldn't this be dealt with by the InventoryWorkaround class?

Get the latest build from here.

@md678685 works for 1.8.8? "builds of EssentialsX above #440 require Minecraft 1.11+ for full /spawnmob functionality." it states on the ci

@vemacs since this was a 1.8 issue on the latest build, does that mean latest builds can be used for 1.8 servers now?

Spawn mob won't have full functionality, but yeah, exactly as it says...?
