The tools from 4.9.2-release (along with that engine version) caused many problems with 2016 (student version - yes, I applied the save fix). Missing data upon binary save, or -the worse part- importing exported FBXs into unreal sometimes stuck onto 75% -> crash or just crashed from the beginning. Sometimes it just worked and imported it no problem. I am currently downgrading to 2015 for that reason (thanks student licences 
)
