A fellow reader who found Minna's comics years
before aRTD and yet is still around reading SSSS to this day? You're a rare breed indeed!
I'd hazard a guess that the robo griffin comic you mentioned is something Minna used to publish in "Umbren metsä", along with her other comics and artworks. That is, before she took the whole place down prior to moving onto aRTD. I honestly don't remember that griffin comic personally, only the comics that came before it. Or rather, SOME of them. I sure as heck didn't remember this one either, though I might've read it years ago:
https://e621.net/pools/2686. That comic is written in Finnish, but there seem to be translations available if you hover your cursor over the text boxes.
I found that link a while ago by googling "Minna Sundberg" and "furry comic", came across some fireden forum (didn't bother reading through all the messages tho) and just went for the link someone had posted over there. With some luck, you might find other hidden stashes like that somewhere, perhaps even the very comic that introduced you to her work.
The comic I first read from Minna definitely predated "Pahistenlistijät" at least a year or two, featuring way smudgier art style. It featured similar anthro characters with big ears and long tails. The only character that I remember from it anymore was a female character called "Penta", who was more or less the straight (wo)man in a group of idiots, looking for some random McGuffin. Minna started that comic once, rebooted it later with better art and ultimately abandoned them both unfinished, all the while she would publish shorter comics and fantasy/antho art alongside them. Then came the great purge for the
Umbren metsä in its entirety. After that, I was quite doubtful that Minna would have the perseverance to get through her "next big project" that she'd announced, which eventually became aRTD. But from then on, she has remained dedicated and steady with her work. With all this in mind (+ how countless other web comics have been left unfinished), SSSS is very lucky indeed to have a proper finale at all, no matter how rushed the pacing has become.
But yeah, Minna deleting her old works is something she's done for years now, all the way from the 2000s. I guess she eventually grew out of her anthro/fantasy art phase, which could partially explain her deleting her original website. To some extent, I can understand this from an artist's perspective. And even from the perspective of a young adult ashamed of their "cringy" teenage-phase, be it furry, anime, goth, emo, or whatever that no longer appeals to you as an adult, and you want to distance yourself from.
It's still a shame though, just how much stuff she has deleted from deviantart alone. Including a work she drew solely with her non-dominant hand, because of carpal tunnel or something, and to see how well and fast she could work like that. It even got a daily deviation award. Sure, she has other daily deviations, but had it been me I wouldn't have removed such an interesting memory from my gallery. Oh well, she probably still has the original work somewhere (at least I hope so), just not available in public.
All in all, I doubt Minna is going to destroy SSSS. It's what she's made as a professional web comic artist, as an adult. It's what
really got her this far and I sincerely doubt she'd feel similarly embarassed over it compared to her "furry phase" from her teenage years. Of course, her becoming a devout born-again Christian IS something that could, theoretically, cause her to "start from a clean slate" once more.... But again, I seriously doubt that's going to happen. SSSS is, after all, still going the get new readers even years from now on. And therefore, from Minna's prespective, it would be wise to leave such a well known comic as a "gateway" to her newer Christian comics.
