Copying tagged glyphs between fonts

[SCarewe (Sebastian Carewe)]

Seems to have broken the copy function entirely, though.

In the latest beta update (3.3 (3325)), Glyphs crashed when you press CMD + C on the contents of a glyph

I am therefore unable to copy parts of one glyphs to another glyph, to hasten speed of creating new glyphs that share similar segments.
