Ideally, check if this mod is the problem.
Copy the folder with the game and from the folder with the copy delete all mods except SVM.
If there are a lot of mods and they are both in the mods folder and in the folder with plugins, it is easier not to copy the game and create a folder and in it already run the installer spt and there already put SVM and create a new profile for the game, as well as in the SVM itself to make settings with bosses, save and apply them.
If the bosses will appear, it means that another mod in the main folder with the game interferes. If the bosses will not be, perhaps BSG something changed in the logic of spawning and the mod simply can not cause this spawn. Maybe the probability is not 100%?
