Whoah - crazy! And you hadn't reported this issue before now?
At first I thought it might be related to this issue, but it seems like it's a different problem. Just so I can pass along all possible information...
Does it happen on either deck?
Does it only happen when you have the hot cue at (what looks to be) the exact same location as the hot loop?
Does this happen if you use other hot cues (eg. not A & B, but others?)
Thanks!
