HeliControl v1.4.6 CH47 issue

HeliControl v1.4.6 by Shady in use. The CH47 helicopter keeps hovering in the air without moving and cannot be removed with ent kill. Requesting a solution to this issue.

This particular problem is several months old now, its very annoying to see the icon constantly lit on infopanel because the Ch47 never goes away.

The only thing I've found that can remove a frozen CH47 is a server restart. I've reached out to the plugin developer but haven't recieved a response yet. Has anyone found a permanent solution to this?
