It has been reported to the PDCMG that there has been some movement in the area of the squeeze in the 2nd boulder choke in the Ogof Draenen Main Streamway. It is possible that this squeeze may have got slightly tighter.

Please take extra care in the 2nd boulder choke and keep an eye out for lose boulders or signs of movement. Following a visit, any reports on the state of the boulder choke would be greatly appreciated by the wider caving community. If you are undertaking the round trip, you may wish to do it in an anti-clockwise direction, until the state of the choke and size of the squeeze has been assessed. Larger cavers may wish to pay special attention to this report

It has been extensively reported that someone recently enlarged the squeeze at the end of The Last Sandwich, a portcullis that guarded the furthest reaches of the system from larger speleologists.

Now it appears the cave is exacting its revenge.

Is this not the Law of Conservation of Cave Passage in action?

Whenever you make a bit of a cave bigger, another bit gets smaller to keep the total amount of cave constant.
