It was always going to happen, said it so many times before, Brexit before anything it seems. I have noted who the brexiteers are on here, so when they start complaining it will be politely pointed out that they voted for this.
We could have a situation where the leader of the largest party isn't actually in Parliament... Very unlikely though. There are rumours (unconfirmed) that those deselected BxP PPCs (who paid £100 to register and in some cases £1000s for campaign material) have been locked out of their BP email accounts and have not access to the support network within their constituency.
