- VCMI will load mods from Mods directory recursively. Submods must be placed into additional Mods directory, e.g. <data dir>/Mods/<mod name>/Mods/<submod name> - submods will be loaded only if their parent mod was enabled - submods namespace for objects will be "<parent mod ID>.<submod ID>" - TODO: Launcher is not aware of submods yet (seems to be working but may behave incorrectly)
