Blademaster bugs

In this video, you will see two bugs caused by a Windwalked Blademaster.

Go here if the video above isn't working.

2 bugs there:

• windwalked BM can't pass through grunts after falling off the zeppelin
• the town portal didn't work when the bm used it right before using the zeppelin

I was able to replicate the bugs on my 1.20e installation of Warcraft so it's not right to say that they're new to patch 1.22. The 2nd bug was a lot harder to do than the first one.
