Bug: Hollow Knight - Unreachable required item

[Shadow-Night-Black]

What happened?

Generated and was playing a hollow knight randomiser (single world/game), using archipelo map mod to keep track of checks. Apon getting every check available to me and being unable to progress, I checked the spolier log to see progression. The log indicated that Mantis claw was the next progression item to get, and to find it at Markoth. Unfortuneatly, due to not having wings/claw I am unable to reach Markoths room (map mod correctly displays this as unreachable).

What were the expected results?

Deepnest_East_10 should not be in logic without Wings/Claw

Software

Local generation

looks like this is another previously-undocumented background pogo so current logic just assumes you can always do the background pogo

Can confirm, with the knowedge that I needed a background object pogo, I was able to reach markoth.
