When I hovered over the next episode (28 May 1985) it said page does not exist. Yet it does with the title Episode 29 (28 May 1985). I am new to this so am not sure how to add links and make changes to the template boxes at the side on the wiki pages.

@Clarky hmm that's strange, thanks for reporting this. This has now been fixed. I will carry out a full audit in case there is other errors. Thanks
