My salamalyon destroyed my spin gear but everything else is fine. What went wrong?

I was testing a screw zeus combo ( strata dragoon g ar, 10 heavy, attack mode seaborg 1 base) vs a stock salamalyon. i launched salamalyon first and when i launched screw zeus into the dish next thing i knew my attack rings and weight disc went flying around the room. the onlything left spinning was the base and when i checked for damage one of the shells was cracked (only being held together by the sticker). All the other parts were fine (at least they seem ok currently)

My question is what went wrong/how did this happen? (Btw one of the side clips was missing from the seaborg base when i launched it so maybe that contributed to the damage?) Is the seaborg attack base just fast enough to cause only internal damage? Is it just cuz these plastic beys are getting weaker by the year? Am i just a macho-wacho strong launcher? I'm curious to hear your insight. Any thoughts are appreciated!
