Cannot select different classes when taking multiple XP levels at once

[Dartaen]

Hello everyone,
I delay leveling up my characters (to get more XP). Unfortunately, I just noticed that when you finally take all those levels that have accumulated, you have to take all of them in the same class.

E.g. when you get 5 levels, you have to take all those 5 levels in either fighter OR thief. You cannot take 3 levels in fighter and 2 in thief.

I do not remember if this used to be a feature in the original game. If not, I'd vote to see it implemented someday.

This was a feature of the original game.

Not sure if these are still being tracked, but this is now a feature in the mod.
