Bug: Copy/paste glyphs paste to wrong layer

[DTF]

Glyphs 1.3.15
I have four masters, Regular, Regular Condensed, Bold, Bold Condensed. If I try to copy a group of glyphs in Bold and option-paste to the Bold Condensed master it pastes the glyphs from Regular Condensed instead of from Bold.

Also, when adding a new master and using a multiple master font as a source, only the regular master can be chosen. It would be helpful if I could choose a different master as a source.

I believe this looks like a job for my Copy Layer to Layer script. (Requires Vanilla.)
