So sorry if this has already been mentioned, but I looked everywhere.

When you are still alive after a hive goes down, and you press r as a skulk (+movement button), there is a leap animation, and you fly forward just a little, but then you glitch back into your original position. No sound or energy is emitted, but it's an odd little glitch

When you respawn, it's fine. Tested twice and happened twice while playing online.

This was a bug in a CM build I believe, which was fixed in beta 1 - I think.

Link to previous bug report.

However, I've also seen it happen in beta 2 but only about twice in the many months of playing and I am completely unable to reproduce it when I want to - to me, it seems to happen randomly but always fixes itself after I die.

What princess says should be correct. It is possible that the problem will manifest if the hive is destroyed when a client is experiencing packet loss.
