I was working on a map and discovered this weird bug.
When you fall through a portal multiple times with a cube while looking straight up the cube will disappear. Have any of you seen or heard of this bug before?

Moved to proper forum.

Fix'd.

Do you mean holding a cube? Or through the same portal as a cube?

(the video's kinda boring as it was just me testing fraps, so you can skip to about 3:00)

it happens if you are holding a cube while looking straight up and falling through an infinite portal loop in a relatively low ceiling. after falling through the portal a few times the cube will vanish.

It's because the game can't load the cube holding fast enough at the speed you are falling and when you are holding it up it gets stuck on the top of the ceiling. (opposite side)

At least thats what I think.

No, that doesn't seem to be it. I played around with it under low gravity and it seems to happen when the cube hits the edge of the portal and doesn't snap back around, if you can keep it from hitting the edge it never happens; there isn't a constant speed or number of times through the portal that it happens.
It just seems to stay on the ground but when you get back to the ground from the above portal it isn't there.

WHAT I SAY
I think maybe GLaDOS steals the box by making a green portal in one of those pipes but keeps you on your way never noticing the green portal while the box is taken to another test chamber (or the same one maybe?)

Its kinda more like a real explination but well thats what I thought.
WHAT YOU HEAR

MY FINAL THOUGHTS
oh well... I hope to come out in somebody else's post...somebody put a red portal plz.
