Problem adding taudecay_UFO to SMEFTsim

Hi,

Indeed this option is not compatible with mode who defined custom propagator.
This is actually a bigger issue for maddm and I will need to find time to implement this.

Thanks for the reminder,

Cheers,

Olivier

Thanks a lot, Olivier, for the clarification!
