What steps will reproduce the problem?
1. single join one scenario from the list (not the last ;))
2. click join all

What is the expected output? What do you see instead?
- I expect to be queued to all scenarios.
- I'm not queued on scenarios that in the list are after the one I manually joined.

eg:
* Available scenarios:
1) Khaine's Embrace
2) Gates of Ekrund
3) Nordenwatch

* Join queue for ekrund (2).
* Press join all.
* Addon joins only khaine's embrace (1) and stops when (2) fails (I guess it fails somehow: found no error in the log), missing nordenwatch (3).

Do you have an error log of what happened?
Noticed no error in the log.

Please provide any additional information below.
It can happen when you're in a group and someone manually join a queue, then you try to join all queues.
Also happens randomly when queuing... sometimes it misses last scenario... :(  (tested only in t1 and t2, with 3 available scenarios)

I guess it happens because when you broadcast the INTERACT_JOIN_SCENARIO_QUEUE or INTERACT_GROUP_JOIN_SCENARIO_QUEUE event, in SuperQueueWindow.joinQueue(id), if the queue is not actually updated (because scenario is already queued) SCENARIO_ACTIVE_QUEUE_UPDATED event is not fired. (just a supposition)
