for some strange reason I can't select bones in pose mode on an armature I've appended from 2.80 into 2.79. It looks like all of the bones are selected, however I can still rotate and move bones if selected in the outliner. Bones will not display as selected either.
The 'selectable' icons are all on, meaning I should be able to select any bone, however this is not the case. No bone will become selected if clicked on in the 3D viewport only if manually selected in the outliner. This is a huge pain and I cannot seem to find a tool to make the skeleton normal again.
