Weapon swapping while on a Rhoa unmounts you and both both are stuck together...

when your riding the Rhoa then weapon swap, it:

1. Dismounts you
2. combines you and the Rhoa on top of each other as if your one walking
character
3. Makes you loose the 100% reduced movement speed penalty when using skills
since your now not mounted

Another bug is that you wont shoot shards from Ice-Tipped arrows while mounted on the Rhoa.

Thanks
