Can't test right now, but it's probably due to local storage being cleared out on exit in incognito mode. Export/Import should still work, but keep in mind that Import automatically prestiges the game.
Thanks for reporting this issue!
I'd suggest you to try on another browser, but I may have and idea on how to solve it regardless. please look forward for the next updates :)
