Whilst The Amazing Spider-Man #5 realigned the series with its US counterpart in terms of issue number, cover and lead feature, this issue skipped the contents of the US The Amazing Spider-Man #6 and presented the main contents of The Amazing Spider-Man #7.

This suggests Conan the Barbarian #1 was delayed. Dr. Strange may have been similarly affected - TBC.
