I am currently using TDJ's stable MIUI build, but this issue has been happening for ages: for one particular contact only, the messages he sends to me are kept in a separate thread from the ones I send to him. I've tried deleting and re-adding the contact, checking for duplicates, but nothing seems to work. I'm not sure if this is a rom specific issue, but I've noticed primarily on MIUI.
Is this a known bug?
