Yes, please, good people from Larian, do something about it! It is not game-breaking, but rather annoying.
My husband and I got to the point of obtaining Tenebrium skill and discovered that now all our One-handed and Two-handed skills matter not anymore. So either we start the game again and ignore weapon skills until Tenebrium arrives to put all the skillpoints there (as an option we can use Moloch, but he can't help Madora or Jahan), or we stop playing this great game for now and see if the whole Tenebrium mess somehow gets fixed.
