RMX Tools with three master MM

RMX Tools works great with two masters.
With three masters it shows interface for all three,
but handle just a two of them?

Yes, this is a known bug. I will have another look and make this work properly.

Thanx Tim.
And Frohe Weihnachten!

Now I have a four masters.
Yesterday I changed values in Scaler Beta window all four masters at once, today I have just a two masters option again?!
A little bit awkward.

After restarting Glyphs it works fine again.
A bit awkward still.
