Overwriting fbx file in Unity 2017.3.of3 causes Maya 2014 64x to crash. how do I Fix This?

Ok, so odd little quirk, I have a legit 2014 copy of Maya and I'm trying to import and overwrite fbx assets that i have already imported into Unity and are in the scene file - active in memory. for fast iteration work this has been a none issue in the past but now seems to cause an odd crash.

Error message says: Fatal Error. Attempting to save in c:/blah/blah temp folder location <- there is a legit location just don't want to type it in since its irrelevant.

Steps to reproduce: 1. Open up maya 2. make new clean unity 2017 project - stock - no extra packages. 2. Go back to maya and make a cube ( make sure maya is set to Y up and cm are the units ) 4. Export cube with fbx exporter into the new Unity asset folder created from the new project ( exporter set to 2014 )( tried in 2012 as test same result ) 5. click back into Unity ( you will see cube in asset folder ( Keep Unity Active do NOT close it ) 6. drag new imported cube into unity scene, ( cube will now be in main scene window ) 7. save unity scene test1 or whatever you like 8. go back to maya and modify cube in someway and re-export- by overwriting existing file inside Unity asset folder 9. Watch Maya crash.

Now I did the same exact setups mentioned above with MayaLT 2018 ( exporter set to 2018 ) - no crash, it updates the fbx just fine inside the Unity scene file while Unity is active. I can close Unity every time I update the file and open it up again but thats not exactly a fast work flow. so it works with FBX2018 but not 2014...

Any clues? I'm looking for a solution that saves my Maya 2014 purchase - I'm not interested in subscribing to Maya 2018 or MayaLT 2018.
