HI I found what I think is a bug when bouncing a mix down when Arranger is on.
open a project with a arranger - mine is around 6 min
turn on arranger track with multiple sequences
last arrange sequencer is not at the end
set loop locators to the whole track for mixdown (even though the arranger sequence is shorter - eg a radio mix setup)
result: you will notice that after the last sequence plays the song will start over again instead of end or silence
