beer went all cloudy?

[hopsoda]

I have a pale ale going in a carboy for about 3 weeks now , it was starting to clear about half way down when suddenly the whole thing went cloudy again
any idea of what's happened?

Could have gotten bumped.

ya possibly, but i don't think it got bumped? the room got a little warmer from having a dehumidifier running close by... so possibly the extra heat sent the yeast into overdrive?

Its cleared up a few weeks later on its own?

o well , this is the first batch i had go clear ... then cloudy then clear again.
