>>1692My mistake. It keeps fixing itself and then going out, so I don't really know if showing an example will replicate the same.
For example, let's just search "Metroid"
https://arch.b4k.co/v/search/text/Metroid/page/1/As I'm typing this, April 10 search results are gone. They don't show up. It only shows April 09 results. However sometimes if I refresh, then the April 10 results appear. Again, I guess things are just fucky. I don't really know how else to replicate it.
As for the original OP timeframe, I was still able to replicate this with the "Donkey Kong" search results
https://arch.b4k.co/v/search/text/donkey%20kong/page/4/It jumps from March 19th, immediately to April 5th. Also provided screenshots. I apologize if nothing said here helps.
