Tonight during my stream at around 4 hours, my webcam and audio was de-synced. Using 0.50b. Was wondering if anyone else was experiencing this?

Happened previous night as well around 3-3.5 hours in.

Would like to add that I don't get this issue at all with v0.48.014b, but I've had it with every version of OBS since then.

Here is a v0.48.014b log for comparison
