Hi, I currently maintain this and all other ZX Spectrum files.
ROMVault names these files *_0.tap, *_1.tap etc., just 3 of them. This bug doesn't appear anywhere else in the current release.
These are managed by a set of automated scripts I've written, which are based on open-source Sinclair database called ZXDB
I cannot make an automated fix without messing a lot more, because I'm already on a newer ZXDB with a vast amount of changes.
Therefore we decided to fix this in the next update.
Best regards,
Helga.
