hi guys,

so my game ran really well up until 30 hours in.
i never experienced any crashes or graphical glitches whatsoever.
but every time i use 'fus' or advanced versions my game crashes to desktop without any
error messages. i tried disabling mods that alter the games audio and physics and set my
audio output to 44.100hz in the control panel but still the same problem.
other shout seem not affected, and like i said, i never had any crashes ever so my mods
seem to work well together. i also use boss for loadorder.
has anyone ever experienced anything similar or knows what could be causing this?
