Bugs (not the bunny)

[Toften]

hehe

I was just wondering...
since I haven't played this game for hundrets of hours (yet)
I've seen people complaining about bugs, but where are they? and what do they do??

the only thing ever happened to me was: at sanctuary, I was running for the drop-pod thingey at the center. And all the sudden, I was warped down some water (looked like the training arena). and my oxigen meter droped very quickly!
was that a bug??
