Today I tried to invite someone to my coop, but it kept saying that the party was full. I had 4 players on my island at the time. I then kicked KroniqL (sorry man but you couldn't get to the island anyway ) and tried to invite again. Same issue. It said my party was full. I don't know if this is a problem or if the max is either 3 or 4. Just please, either can someone fix it or inform me that the cap is 3 or 4. I have this person homeless right now, I need this to be solved ASAP.
So, if i'm not mistaken after you kicked Kroniq there were still tree other people on your island not including yourself?
