Having seen this thread (https://forums.taleworlds.com/index...e-in-game-edit-mode-outdated-incomplete.5623/ from section https://forums.taleworlds.com/index.php?forums/module-system-documentation.12/), I was struck by the fact that for 16 years it had not been completed even though it needed little effort to finish it. Suddenly, time froze and I realized it was my destiny to close the circle and complete the topic. I felt that TW had been struggling with misfortune with Bannerlord only due to failing to finish the development of the above-linked tutorial and I was the chosen one to end the streak of bad luck of the company. Now I enter the scene to fulfill the fate.
