One theory i would actually bet money on, is this:
They chose to rework Monsters with Slash to address the fanbase (as crazy as it sounds), the vast majority thought that the cellphone clip was The General, even Fernando vaguely joked about that, right? Think about it, why wouldn't they follow the path of Absurd and HS and just go for Atlas + Perhaps? Why would they specifically chose to release what was considered the holy grail and then its "follow up" which is actually a completely different song??? They could've saved themselves from the risk of messing up like this, and people would still be excited about another EP like the one we had in 2021... But it was a smart move to capitalize on the hype while pleasing the hardcores, (the 9 min mashup on youtube quickly reached like 7k views on YT before it was taken down, so no, while the vinyl money could be insignificant next to the NITL cash, it's not only 34 forum nerds the only ones who care about this).
So, Monsters was the one meant to be released as a vinyl only hidden track after TG. Similar to "Her Majesty" on Abbey Road, it was going to start playing after some weird seconds of silence... this, as a nod to the hardcore fanbase (with the obvious main objective of selling the shit out of it, that as the end goal all along, of course). It was found out not too long ago that it was registered as "The General and Monsters" but they probably didn't wanted to give that away too soon, and that's why it was never listed as that on the official store, for like 2 months or so, maybe a month and a half ...
Enough time for Rock Radio Italy, which got that info (likely incomplete and not detailed), and since The General was the only track listed across all of the GNR official media and stores, they put out the exclusive news that The General was actually going to be released as a vinyl only track, never to be released on digital formats.
That's basically it, this could be one explanation for all of that i guess.
So what happened days prior to the 27th? That's where the other possibility may come into action here... the quality was a disaster and they tried to backup and get rid of Monsters and save it for a next release, but someone got it before they could follow trough without us knowing, it was too late.
Now, if we only get The General on streaming services without the hidden track or without Monsters as a playable song next to it... then i'll be even more confident about this 👍
