losing items during instance teleport
What appears to be happening is that you’re consuming the potion and the game is trying to change your instance, so there isn’t time to apply the buff. I don’t know that there’s any way to prevent that from happening, without a lot of new code. So, even if ANet agrees with you that this is important, it’s going to be ages before something changes.
In the meantime, don’t click the ‘ready’ button until you’ve consumed your potion (or consume after you arrive).
