Hi! I found another problem. My hero has level 37 and every time he level up one step and your dialog screen with skills appears, and after i choose a skill, the results is the donwgrade the skill of the hero. For example, i want to upgrade advanced sorcery to expert sorcery. The game dialog shows up, i choose expert sorcery and when i look into the hero secondary skills i see basic sorcery. Strange! Then when my hero accumulate enough experience to grow up a leve, i choose expert defense, but i realised that is downgrade from advanced defense to basic defence. All works fine until hero level 37, when total experience is 2002241. It is strange that when i right click on hero sorcery secondary skill it appears a dialog from New Upgrades Script to construct Hall of the Pit. Until your last update of the script this strange things not happend.
