I've been seeing this to, it happens with ANY race/class/difficulty setting. I first noticed it when I'd set my resolve to 15, which gets auto-bumped to .. 15 and then drops to 14 when you choose another culture. It SHOULD get bumped to 16, and then drop back to 15, in this situation, but it doesn't. Since then I have noticed that this happens regardless of what the stat value is set to, thus always permanently removing a stat point that it should not be. OP is correct in his statement.
