I’ve been trying to edit a custom scenario for starting in a airliner crash but it seems incredibly finicky editing the mapgen and has some sort of weird co-decencies with the lixa lab causing it to malfunction. For some absurd reason deleting the “place monster”, changing the chance of monsters spawning, or even changing the monster that spawns causes a whole bunch of cascading failures seemingly related to lixa labs in the error reports. Some even cause the game to not load entirely
