switching from CREATIVE into SURVIVAL

we use an essentials command /ci (clear inventory) after using this command in creative to be able to switch in survival

the items you had in creative seem to pop in survival

AS: latest DEV
spigot : latest DEV
essentials : release build

So your server is setup to automatically call clear inventory right after a game mode change?

Or is the clear inventory called before the gamemode change?

You can simply deny a gamemode change if the inventory is not empty using the configuration. Due to how essentials does the ci command, this may not be possible to override.

Closing as "cannot resolve at this time". I'll keep it in mind though.
