I had a trip in on Friday and the final section of Second Choke after dropping through the hole with the sign seems to show signs of movement. I normally do a short section in the stream before climbing up a couple of feet and then sliding down passed a pendant that does not quite touch the boulder beneath (about 1cm short). This is now touching (and overlapping, >2cm movement) and a boulder above this one also seems different and may have dropped a good bit more, when I viewed it looking outwards.
There is the easy, but damper option of following the stream all the way through this section and thus avoiding these boulders.
It was confirmed by another group on Saturday, that it was different from normal.

Take Extra Care !
