In the "Work for Idle Hands" Mission, it gets to a point where a bunch of confetti pops out of nowhere and starts causing lag. The picture below shows the confetti spam. This problem happens in High graphics resolution. I want to mention now that this problem also arose in the test servers, so I thought that I'd bring it up again.
