Not sure if others are as clueless as me, but just for troubleshooting, I went and switched back to the original OBS v0.657b, and copied over just about everything I was doing in OBS Studio (including making everything global like OBS Studio automatically does), plus I added somethings like image slideshows . I didn't have any problems the entire night with v0.657b. With OBS Studio I was crashing 2 to 3 times a night mid stream. My streams are 4 hours long.
Anyhoo, hope someone can figure it out!
EDIT: Oh, and another heads up. Sometimes when studio was crashing and I'd restart it, OBS Studio wasn't able to recognize my webcam (C920) until I went ahead and unplugged my webcam and replugged it back in. Sometimes OBS Studio wouldn't even start up until I went ahead and reset my webcam. This also affected my Avermedia C985, for some reason OBS Studio wouldn't recognize the device even when I'd disable it and renable it, I had to restart my computer since it didn't have an easy unplug and replug solution since it's internal.
