If you're playing SR24 it cannot be removed. If you are playing DSCS you can remove the mod BUT you have to start a new game or resume a game that was saved BEFORE you added the mod. I'm sorry you don't like the quest. As I said in the readme, I know some people will prefer DSCS and that's OK.
If you want to give it another chance here are possible reasons you think it's broken: the bot is not 100% Integrity, the bot is not 100% Psychocore Stable, you have the bot marked "do not sell", the bot rating is too low, some parts in the bot are rated too low, the skill is wrong (combat when you need sex or vice versa). If you assigned the bot a role or sent it on a mission the integrity and/or stability may have been reduced. It's safer to put the bot in storage until the mob shows up so it remains at 100% integrity and stability. Remember you can check the Journal at any time to see exactly what bot is needed next.
Your complaint gives me the idea to add some way to check bots to see if they would satisfy the mob. I'll give that a shot in the next release but that won't help you now.
