Not sure why this is happening. I'm in on a Vulcan character doing some explore the cluster missions and I run into some trouble and need help (I'm LT5) so my girlfriend who is a rearadmiral hops on to help me. I tried to invite her to my team and I get the following error.
"Error creating team: Allegiance does not match team"
Both characters are Federation characters and she was able to invite me properly.
