I figure it's a good time to try for the Crushing Star now that I'm nearly Lv. 75 (2nd Legacy) and have all my Co-Op mods and boosters purchased. Is anyone interested in helping a fellow player out? We should start immediately, preferably.
I'm getting "Unable to Join Party" messages from your invites It sometimes happens with certain players I party up with.
Both you and your buddy need to back out to the main menu and reconnect to multiplayer. If this still doesn't work you need to find out the right combination. Like who needs to be the leader, which player joins that leader first. Maybe you will need to promote someone else so the 3rd can join in.
Yeah, I've been through this before, many times. Sadly, I got one of them **bleep** Gigaset routers, which is always NAT type 3 even if every single port ever is opened up. I can connect with most people if I reset my router and then join, but even then disconnections tend to happen.
It makes things difficult and this is why I generally don't do parties... but I really want that star
