Yes. Recalling leveling only once, while experienced the temporal hang at least three or four times. Sorry wasn't exactly clear about that. (not sure about the sole skill increase though)
To put it into perspective. There is often a short period after an attack when the game won't listen to orders yet. I see myself click and try end turn too early and then have to do it again. What reporting here, albeit it feels the same, is that it lasts much longer than usually. To the point I thought the game is frozen. But then it resumes all right.
