Conflict can destroy a team which haven't spent time trying to deal with it.
Don't neglect problems, they will only fester and turn relationships sour. Within all forms of relationships - romantic, familial, friendly, or among colleagues - communication is key. Make sure nothing is left to fester and that no misunderstandings exist long enough to spoil a relationship.
