Shoey-SkiI have a pair of marker griffons, got new boots last year so I took my skis to the shop to have them recenter mounted to fit the new boots only to find they were to lazy to remount so I guess they had just moved them up to the very last bit of the track and they moved but some how stayed the season then the last day I couldn't snap in so I went down to the ski shop and the guy pulled my whole back binding off my ski with no effort said I was lucky it didn't happen in air and that I should be happy my legs not broken or worse.
Basically op go get your bindings remounted at a good shop!
Dude that same thing happened to me but with jesters. I bought new boots and had them adjust my bindings. Picked them up and drove all the way home (40 min away) and didn't realize until I started to mess with them. I could pull off both heal pieces with my hand. They were hanging on by the very last thread!
To be fair to the shop, I went back and showed them and they were very apologetic about it haha. Granted they should've remounted from the get go, but when you lock the boot in they felt solid. I'll still go back there since they've been good to me other wise. I'll just be sure to check their work before I leave.
Just glad I saw it before I skied it or that could equal death.
