@Protok St On a completely different note, I saw
this post of yours where you identified a flaw in the code for spawning colossal aliens and say that you figured out a fix, but never actually explained what it is. Is it complicated to implement? I've been getting annoyed at how by the time I can afford to go after a siege worm for the associated quest, and/or have researched the tech for leashing colossal aliens, they've been long driven to extinction thanks to the overzealously xenocidal AI players.
PS: I tried DMing this question to you, but keep running into a weird error.
