so i notice that a corner of the ceiling in my bathroom has formed a bubble (i dont know how else to describe it) and is starting to drip water. I am terrified it is going to burst open and flood the bathroom. The rain isn't stopping anytime soon and I cant call the landlord/expect him to do anything until tomorrow anyway, I don't think. Is there anything at all I can do to prevent this from turning into a disaster? What would you do in this situation?
