I just changed from the white team to purple. I made a trade and did not get the team bonus. I know from previous experience that you have to change colors first, which I did. The nation I traded with is Ethelredia. I edited my nation, changed to purple, then, immediately, accepted the trade. The trade was accepted, but I did not get a bonus. I know the work around is to redo the trade, but this should not have happened.
thx
