Restart issue

[S'bass thulu]

Working on the lvl 99 boss achievement I've noticed if I'm getting a large amount of materials coming in and the game is figuring the level up points, I can restart before they're set (calculated) and in my restart I'll have killed one or two horde but will be on lvl 14, or above.

NBD to me, and pretty rare when it happens. I've done it twice now. Everything else works fine. My level up is set to manual. I'm on the beta.
