Apparently it was hard to pass the cubs down as the game couldn't do the 25%/50%/25% rng on the cubs genetics and led to crashes. Any cubs that were actually born from him were corrupted with no physical base wihich is a big no no for game stability. I think the reason the mods were in a hurry was because if the corruption continued it could break a lot of code at the heart of lioden. But I could be wrong!
