Large-scale changes in cells and clusters (trees...) of game-world lead to problems with suture synchronization. In the case of "A Forest", I chose only 2
additional mods that require attention - America Rising and Forth Strong Expansion. Therefore, they are included in the main assembly as mandatory.
