Hi k1lly0u, hope you're keeping well. This isn't a big issue (for me anyway), so don't feel the need to give it any priority. When the "eject" flag is set on a zone, it only seems to work when players are on foot, not if they are mounted (e.g. in a boat or minicopter). Tested with ZoneManager 3.0.11.

Fixed in 3.0.12, so I'm marking this "solved" - thanks k1lly0u!
