0007742: [FLIER] Tag causes several issues, including ceased movement of creatures and zero invaders as well as FPS issues.
Since this issue to be somewhat ignored here it is:
Every game I started since .03 has this problem.
The first months are fine, creatures enter your site including hostiles. Then after some time some flying creatures WILL get stuck mid air. There is no way to prevent it from happening and it brings wildlife and invasions to a complete halt.
I played several worlds now and it keeps happening and causes:
- existing wildlife to stop moving. (includes cavern creatures)
- new wildlife NOT entering the map.
- invaders or megabeasts NOT entering the map as well.
- at least slight FPS drop.

Due to this issue, hunters have nothing to hunt and military is quite useless as well.

Caravans DO visit from all civs as usual. Migrants work fine as well.
- Start game in biome with flying creatures.
- Play about half a year. (Sometimes more, sometimes less).
- Zoom to creatures and watch them.
  If they're still moving everything is ok. If they stopped it's broken.
Workaround:
Removing the [FLIER] tag from all raws before world generation removes all stated issues of this report.
Easily done with Notepad++

I use MayDay DFG so I can't provide a vanilla save. (I have no idea if saves with graphic packs are revertable to vanilla so I uploaded the whole package).

Even more information inside the forum: http://www.bay12forums.com/smf/index.php?topic=141280.0 [^]
Others are getting those issues as well.

I set the severity to minor since the workaround is rather easy to do.
Without the workaround however I would consider this issue as a major bug.
No tags attached.
