Posts on thread all mixed up and repeating themselves

[WeeDangerousSpike]

This thread www.mumsnet.com/Talk/am_i_being_unreasonable/3645154-to-call-gross-misconduct?pg=15&order=

Starts randomly repeating itself for the last 3 pages!

Very weird and confusing, and possibly connected to random posters being marked as the op and OP's op being moved down the thread?

And some threads, inc this one don't have any messages in them when I open them.
