I have been having an issue where I will get a communication window from one race and it will immediately get overwritten by a communication window from another race. I do not currently have a save file where I can reliably reproduce this. I am currently playing on a Large galaxy with 9 opponents. I also had it happen on a Medium galaxy with 5 opponents. It has been long enough since I last played that I do not remember if it happened before Intrigue launched.
