I contacted pgh support and got that firmware update for the Taiga too, to no avail.
The OT MIDI clock definitely has problems with some modules e.g jomox mbaseII. I’m sure there was another that had this problem and they did manage to solve it- might have been the Preen FM3?
Turning the OT MIDI clock off helps with the missed steps but then obviously you can’t use it as the main clock source.
The cc mod assign problem must be a seperate issue as it doesn’t work regardless of whether the clock is off or on. It did work for me using a different midi sequencer so it’s definitely the OT causing the problem.
