Placed shared components become mangled after updating from Library

For the last few days, shared components become mangled after I update them (based on recent changes I make to the master component that is located in a shared library). And by mangled, I mean elements change position and size, plus some just get removed altogether. This isn't just a one-off either. I've gone back to check and update my shared library components many times over the last few days and it keeps happening. The files where I am using shared components are all messed up and I have to spend hours fixing them manually. 

Even the components in my shared library file are getting randomly messed up as well. How on earth are their elements moving around drastically and also missing some elements at times? Many of which haven't changed in some time (a month or so). This is beyond irritating and causes me massive headaches with getting work done while wasting tons of extra time trying to restore my designs to their original states.

My XD version (on Mac OS) is fully up to date. I have posted a small sample/example of what is happening when I access files using shared components.
