was running synthcorp id with synthcorp factio as best, tried to go to Leeds, was enemies to everyone there, after getting blown up, respawning in Manhattan, my IFF was now LI Navy, with synthcorp right above, still havent figured out how it happened, Didnt notice till someone told me about it.. He also told me how to change it with droprep. I'm assuming that it only changes the bottom rep on your list.
Thats also when I found out about having 2 id's, as I had synth and freelancer. sold the freelancer id. Mainly Im very puzzled as to why my LI Navy became prominent. Running in a 2k ton freighter.
Certain rep decrease or increase rep to other factions. Like when you are synth and pew rouges you also will increase the liberty lawful factions like the lib navy. Similar when you think visa versa when you are rouge and pew lib navy you will also increase rep with groups like the lane hackers but it will decrease that of the lib lawful's like lib navy and police.
