When enabling a multi-out instrument track (eg Stylus RMX, Breaktweaker etc) from a project saved with that track disabled, lots of duplicates of the first output appears in the project window, and some random ordering of the rest, then wild ordering in the mixer. On my recent test, there were no less than 8 Stylyus RMX A outputs and 1 each for the rest in the project window, while the mixer showed just the one regular track. For Breaktweaker, it showed 4 main outs, aux 4, aux 5, another main out, then auxes 1, 2, 3 and 6. In the mix console, these tracks were ordered wildly, with different outputs from different plugins interwoven.
