After killing heli we don't get any crates.

how many crates have you set it for ?

Hi,
I chose 3 crates for my setup. What is amazing is that no one seems to know where the problem may come from and the creator of the plug-in seems to the absent subscribers.

Same issue here.

This is the intentional behavior if you have called the helicopter with the permission "helicontrol.nodrop". You may have granted this permission with a wildcard, and it was probably stupid of me to make the permission nodrop instead of the permission granting drop, as people often give themselves all permissions in a plugin. You should try revoking the permission "helicontrol.nodrop" from yourself or your group using the permission system and see if the issue still persists.

You may also notice that crates from a helicopter spawned via server console (RCon or directly) should spawn and be normal.
