I just completed the Railroad quest to set up Mercer Safehouse as requested by PAM, but I am hesitant to send settlers or place a recruitment beacon there. Is it okay to have settlers settle it or does its covert function mean that I should just leave it empty?
In other words, are there any reasons that I should leave Mercer Safehouse uninhabited (such as penalties or being locked out of quests) or can I go ahead and send some settlers over?
