Problem with new spells research. A bug?

Hi.

I am not sure is it bug or no.

I have problems with researching a new spells after some time playing a SK.

As I noticed problem connected to “loading” saved games. Then I play without loading – all is fine.

I bought game via Steam. Maybe it`s important because I had some problems with games purchased via Steam before. Today I downloaded last version of SK – but it doesn`t help.

Below could be several examples, but I cann`t download correct print screens to this forum.

On the first we could sow that all is right. (Turn 17 – 7 turns till a new spell research).

And on the second we could sow I have no any possibilities to research spells (Turn 32).

I coudn`t find any suggestions in game manual and coudn`t find a decision within a game. Any changes in mana management or capturing a new shards doesn`t help too. As I found in this forum problem could be connected to autosaves, but then it as a REAL BUG which was not fixed within several patches.

If anybody could help to solve this problem – thank you in advance.

P.S. It does not matter for me but after I freed a champion in my first game of SK - quest “break a champion`s curse” was still active in my “reports”..
