Does anybody have a save file in between or right before the Vesani Vaults main quest?

My game bugged out and it deleted my only manual save and all autosaves which automatically synced to Steam Cloud. I had completed every piece of side content possible till that point except the MF Twisted Paths area, and was just at the starting of the Vesani Vaults - the Golem foundry or something, the first area you can go to after the entrance.

I think I'm just gonna quit the game if I am not able to find a solution, no way am I gonna play through 50h of content again. Any other solutions also appreciated, I've already submitted a support ticket to Riot Forge and waiting on a reply atm.
