To prevent sound spamming when you're sleeping, Sonmia sets the sound effect volume level to 0% while you're sleeping. This stops the IC2 sounds as well. When I wake up, the sounds work fine, but the IC2 sounds aren't playing. When IC2 tries to update it's sounds and play them again, the entire sound system crashes.
This is fixed by disabling the IC2 sounds, but it's kinda disappointing that I have to do that because the sounds are so cool :\
