I keep getting this error.

I have been getting this same issue. Do you perhaps have your FancyDrop set to "Players can shoot Drops down : True" ? 

I just turned mine off (To Test) as I was getting this issue when players are taking the Airfield Event Plugin which has Stationary Airdrops and NPC's.

Thinking with shooting the landed airdrops FancyDrop is trying to make them fall faster (If that makes sense, Im no dev)

Not sure if you have other plugins that drop Airdrops? Could be something similiar.

Thanks for posting.

I'll edit back if this solves or remains.

Ice

"Edit: I can comfirm that "Players can shoot down the drop": true" Is causing the conflict,

Set to False to remove console spam

Yes, mine was set to true but is now turned to false. I wasn't sure if it was the Fancy Drop bugging out or the Santa Sleigh plugin that I had added for the Christmas event. Everythings working now. Thank you for the reply <3

Glad it working can you change the status to solved :)
