Bug in regular campaign

I calmly completed the main task "Liberation of Shiel", and after Commander Tinar "gave me Urtan warriors", the warriors did not become mine, and my character began to gain experience endlessly, reaching level 50 in a few minutes. I took elemental magic lvl 20 and white magic (life lvl 10. Now with a staff for white magic 7 (damage 9-13) I deal ~ 70-80 damage in hand-to-hand combat (excluding armor). Should I be happy or sad? And yet, this is a task bugged because I healed the commander after I cleared the location (I also called dryads), and I did it with a circle of human power, and I turned off the elves after mining lanya, and the rune altar (summoning heroes) did not activate.Now the items "Capture the circle of power of the elves" and "Punch the way to the east" are not completed, but I did it. I destroyed the robber camp on the first run, and when I got the wallet, the item "Teach the robbers a lesson" remained unfulfilled. What to do?
