Live11 Macro bug

Hi there,
I just noticed a pretty bizarre bug that I couldn’t duplicate in Live10. On Live 10, the efx mode of my Beatstep script works so that I can control the first 4 Macro-Parameters of a device (on a selected track) with my first 4 endless controllers, the other 4 I can control with my first 4 pads. Now in Live11, in my older sessions only random macro controls react to my controller. When I make a new track (or a new session) and load an instrument rack, the macros react fine. As soon as I map anything from an instrument to a macro, my controller commands don’t seem to get through – though I see midi coming into Ableton. The same is true for Efx racks, audio and midi. Is this the case for everyone? I hope this can be figured out, because this is a biggie 🙁
