When joining ATC ground at Heathrow. Another ATC account can join in as well and can cause tons of confusion when 2 accounts are conflicting with each other’s orders. Another thing is if one of the 2 leaves, it causes the still remaining account to lose their role and sit in a sort of “limbo” role. Where you can’t do anything other than sit and wait until another account joins ATC ground and reactivates the frequency.
