Charlie Muggins is left in the field sleeping in a brown-patterned sleeping bag by the Potters.

Bulls don't actually charge when they see red. They're colour-blind and are provoked by movement, so the bull should not have started charging until Harriet gets up and starts running towards the gate.
The sign for the "all night rave" states that it's taking place on Saturday 10th August. Saturday the 10th August took place in 1968 and the events in this film clearly take place in 1969 based on Sid's "Miss throw up 1969" line. Therefore 10th August 1969 took place on a Sunday and it seems that the filmmakers forgot to amend the sign to match continuity with the release of the film and the events taking place in 1969 as opposed to 1968. Filmmaking took place in 1968 which is how this error has occurred.

When Mr Muggins, and Mr and Mrs Potter struggle to get undressed in the tent, the ridge pole of the tent collapses behind Mr Muggins, but the tent stays upright and in later shots the pole has been reassembled.
When Sid is trying to talk to Babs through the wall in the shower block, he tells Bernie he can hear her, what is actually heard is Babs saying, "Sorry for bursting in on you last night, sir," to Dr Soaper from the hostel scene earlier in the film.
