Falling through the floor

Shortly before 6pm (GMT+1) I somehow fell through the floor at Hawkers Alley. I am unable to replicate it but I did manage to free myself by jumping onto the small fishing boats at Fisherman's Bottom (needless to say some players were startled by my appearance).

I did not test to see how far I could go as I didn't want to break anything.
I think it may have been caused by broken clipping as I walked up a tiny ramp to enter one of the merchant areas, but again I cannot replicate.

Definitely the funniest bug I've encountered so far.

Sometimes that can happen due to interruption of data flow from your connection as well. See if the Devls say anything here, interesting bug.

Had it happen a few more times since I first posted, I'll update the OP with screenshots and info later.
