I'm pretty sure he was attempting to say something along the lines of the giant black spike that appears due to a weird mesh.
"Have you ever recorded a replay and then a line (mesh spike?) appears (likely after crash) but when you aren't recording it doesn't happen?" Is probably what they're saying.
Finals might have killed me, but BeamNG has brought me back. Never really tried off-roading, but I have to say, hell of a lot more fun than Snowrunner.
I'm making a vanilla config pack for myself and decided to get screenshots of everything that I've made so far.
