Mods are used to spawn the CERF after seeing the issue, can confirm that nothing modifies the CERF at least involving the clamps
This was done in response to a similar issue in #help-and-support, and appears that CERF clamps jump a bit when pushed in with a decent bit of velocity. Video shows pushing in the left clamps before drifting to the right and the first collision didn't cause the bug while the second one is.
Unrelated, but something I noticed while recording this (and i switched to vanilla after to confirm this): is the ER-42 trajectory prediction not supposed to appear when using manual controls?
