Server Backups for my primitive plus server were overwritten during downtime and server transfer.

Ok so after the recent Ark Genesis update all primitive plus servers were broken and unable to start. During that period rather than have my server be idle after i paid for it i decided to convert it from Primitive Plus to Survival Evolved. I read up in nitrado faqs i think that swapping wouldnt have been an issue because server backups were constantly saved. I moved forward with the transition and used the same map as primitive plus. I was on the survival evolved server for almost 2 weeks (which was way longer than expected) because that was how long it took Wildcard the game developers to fix the Prim + server issues. Once the servers returned i converted my server back over to Primitive Plus only to find all my data was gone. Everything that every player had built and all items. Characters were intact but world reset. I tried to restore back ups as far back as possible but i was only able to go within 2 days of the actual relevant save date. Everything prior to that has been overwritten and i cannot back it up so my server remains blank. Ive attempted every kind of restore available via the backup page and gone back as far as possible cannot get to the day when the server issues first arose. I cant imagine having everything deleted. Can nitrado support see more backups than I can or is that it and my save files gone? I tried to explain my issue as clearly as possible sorry for long read.
