Yoga I am rooting for you to find a new buyer. FX (and everything crossed) 
Knitted
- basically no words but it sounds awful. I hope your chain is now intact and FX that you have a speedy completion.
Ann that's annoying. However if you have paperwork showing it's been booked in and you'd be happy to give them the money towards it, then I don't see any reason why they shouldn't go ahead on that basis?
Thomas sooo tempting, but I'd be very nervous about him offering so much money and then pulling a fast one the day before exchange and dropping his offer. Good for you for sticking with your buyers - it might be worth dropping this news to your EA and asking them to pass it on, basically to say that you are sticking with them but that they need to do everything possible to expedite their legal process (i.e. keep the pressure up on their solicitor so that it all goes through quickly).
Sausage how stressful - last thing you want to happen! However a £35k reduction sounds serious so hopefully it will be snapped up quickly and the chain will be intact again soon.
Perhaps aaarrgghh!! How frustrating! Why it is the simplest tasks seem to take ages to sort? FX they get it scanned across ASAP.
Giz glad to hear mortgage offer now sorted. We've approached 3x removals firms for quotes on the basis that if our preferred firm isn't available when we - finally! - have a date, then we have another 2 as back-up if necessary. Hopefully one of them will have some availability...
Munki Oooh I'd have zero problem at all telling them to fuck off! They have the internet, YouTube and a brain - figure it out yourself! After the way they've behaved I wouldn't be leaving a single instruction booklet behind either 
Fialor It's awful, isn't it? The whole system is a complete shit-show. FX your chain gets reinstated ASAP.
Lubey I'm pissed off for you - what a horrible situation. And the powerlessness as well. How can people be so thoughtless? Is the house an absolute dream house or could you walk away from it? If you could, and there are other houses you're seeing which might be suitable, then I would seriously think about walking away. Even once they have found somewhere the whole process relies upon people being proactive and moving things forward. Honestly, they do not sound like the kind of people I'd want to be in a chain with - I'd be very nervous about them causing problems during the legal process. If it is a dream house then if you can go into rented to wait it out, then that would at least remove the stress of worrying about losing your buyer. 
Puss welcome! Welcome to the land of unbelievable stress!!
However the good news is that if you are only buying then it's not quite as bad as selling at the same time - I'm not joking when I say that the rate of greys coming through in my hair has tripled over the last 6 months!! Searches at the moment are coming through quite quickly so I would wait and get your mortgage offer done first, as the search pack usually costs £200-300 so no point in spending that money if you have an issue that comes up with the mortgage lender.
Pixie bloody hell! (Welcome BTW). I think I'd be lying down in a dark room clutching my gin bottle after that 
Phew - think I have caught up!! All OK with us. Hoping to exchange on Monday. I am currently - obsessively - checking the bank details for the deposit transfer...
