Looks like the little icon image for the Airdrop is missing or was deleted from the image hoster.

The developer fixed the heli icon, waiting on airdrop.

Merged post

I used this link.... its not perfect but good enough for now https://i.imgur.com/hsmozY2.png

Actually, Heli, Hostile and Airdrop are all still broken as of this post time.  Heli is not fixed.  :(

Heli is fixed, just gotta delete the old config and reload the updated plugin v1.0.3.

The plugin has been updated with a new link: https://i.postimg.cc/D0jShLfB/dble6vf.png

No...this plugin and Magic Heli are still broken.  Fully deleted the mod.  Verified no config or data files exist.  Reinstalled.  Verified the new image is in the config.  Still "no image available".  Tried to host my own image on multiple online hosts...works other places on my server...doesn't work with this plugin. :(
