Yeah, I usually don't even look what mods are available for a game until I've played it two or three times without mods. It just feels... wrong... to mod a game before I've experienced the whole thing unmodded. This CASM mod clearly doesn't involve any major gameplay changes, so I'll consider installing it, but I think I'll try reloading my Vault 87 save without CASM first, and if that doesn't work, then install it. I know that's stupid, but whatever.
Also, what fight are you talking about? I used a Stealth Boy to sneak past the Enclave soldiers on my way to speak to Eden (there was a brief fight when I accidentally bumped into one of them), then after telling Eden to self-destruct, I just ran screaming all the way to the exit while the enclave just fought their own robots.
