2. Entered as additional member. i.e. 0 mins past, rest of alliance already inside.
3. Upon entry none of my alliance members showed on the map, instead all of Twin Adder showed up.
4. Subsequently I could not attack anyone from the Twin Adder at all (The alliance I was in still showed as friendly, just didn't appear on the map)
5. Exiting the session to the title screen and logging back in didn't fix the problem.
