Any chance you'll get around to fixing vehicles, I'd even take a revert at this point; desync and map fall throughs are at an all time high. Swimming need a massive adjustment since 1.19 it is near impossible to get onto a rock or any surface while in water. The inertia addition pretty much broke jumping; I understand that modded maps are not your problem but since the community has kept this game alive while you sat back and did nothing over the years it would be nice if you took them into consideration.
