AECOsim (SS6) to LumenRT (2016) Export Error

When exporting to LumenRT from within AECOsim the following error message is displayed:

ASSERTION FAILED:
false
c:\dev\eon2016\vue\source\emotionfx2\core\source\vector.h:212
(you can attach the debugger)

I click ok and the error doesn't disappear nor does it continue to export.
