Check the flight path the flyer would have taken to the destination flag (around 80-90% of the world height near the ceiling) and fly the route the flyer would have taken and see if you can find the flyers - most likely stuck on some part of the terrain - I would like to know which.

Will check it out.

Thanks. You can test by spawning another flyer, equip it with a leg ring and manually send it to the flag in question, then follow behind it on another flyer. I'm currently working on a system to detect the world ceiling more accurately to avoid problems like this from occurring.

I always recommend equipping flyers with GPS trackers so that you can locate them in the event of something going wrong.

We will try that. We found the Alpha Wyvern just sitting on the ground. Along the boundary wall on the west side.
