PLEASE HELP!! LOST 16 LEVELS

[XxLtTangXx]

So yesterday, after the new servers were put online, I stayed on till I could put down stone foundations (lvl 20). Got my foundations up, and logged off at lvl 22. Only to wake up, get on, and find my character is now lvl 15 and I lost the engrams, luckily my foundation are still up. Is this intended or is there a bug? Is there anyway to get these levels back?

Im playing on server 294, i was level 25 when i logged off and when i logged back on i was out of my tribe and level 18. so the metal tools i made at the time are unrepairable by me until i regain my levels. luckily a nearby tribe is repairing my tools if i give materials. geuss this is to be expected in the life of a beta.
Edit: I just thought i was level 18 when i logged in so im assuming it was something to do with the saving.

Most likely this was caused by the server not saving properly or at all. You might want to contact an admin for that server and ask them if there are any known issues with their server not saving (or check from them how often their server saves). It could be anything from every few minutes to hours in-between saves.

There was notes posted about some servers having issues with saving and caused roll backs. Nothing they can do for you. It's part of the testing. It suck but it happens
