leveling and arch mage bonus questions (possible spoilers)

[PRGFool]

these two are questions, I don't think the game is counting up skill points for leveling up correctly. I trained fives times on armorer(at the same level), which I believe should have given me +5 on endurance upon leveling up. In the last 5 times I have leveled up the biggest attribute number to select is 3 and I know that I have had a couple of fives because I spend so much time making potions. I am a lvl 15 battle mage and my alchemy skill is 82 and I have never had 5 to select for intelligence upon leveling up. Anybody ever heard of something like that? (I have loaded the 1.1.511 patch prior to playing this character)

The last one is, when you get to be arch mage which my character is now, you get to put one ingredient in the chest and get 10 back after 24 hours. I put in nirnroot and it did not give me 10 back after 24 hours. I took the nirnroot out and put another ingredient in and then immediately selected the chest and there were 11 of the ingredient I had just put one in the chest. I guess nirnroot doesn't count as an alchemical ingredient because you don't/can't use it in any potions????

To get a 5X mutiplier for leveling up, you need to have had 10 skill increases not 5. Every two level increases gets 1 multiplier(to a max of 5).
