Very useful addon.
But for already a week or maybe even more there's about 20% chance that [start battle] button will make you leave queue instead of accept invitation.
And it becomes rather severe when you get your AV queue cancelled after 1h+ of waiting.
How can we fix tit?

uncheck 'Replace Enter Battle Button with count down'

this might happen if you are in combat and battle info cannot find correct button due to blz restrictions
