So I'm pretty sure there are death barriers that are either too close to, or directly clipping through, some geometry. In this clip I believe TKO hits a death barrier. It actually happens when hitting a lot of door frames on this map. My guess is that hitting it from the right angle with enough speed will make you bounce downwards with enough momentum to sometimes clip through the ground a little and touch a death barrier right underneath. Could be something else too, but it's easily repeatable under some door frames. Any suggestions are welcome.

I've also seen lots of clips of random deaths around/on vehicles on different maps. I haven't been able to recreate some of the ones I've found and I think they might be quietly fixing them. This map does seems to have a lot of these spots, though. Here are some examples where I've been able to recreate it on this map and on other maps.

In this video, the first instances are me making myself briefly lag mid-jump, which I think makes my landing rough/laggy enough for me to touch a death barrier underneath the ground, which might be what's happening in some clips. It only happens in some areas on the map (and as far as I know only this map), which makes me think it's not somehow related to the anti-cheat or just the lag itself. To be sure what exactly is going on would take more testing, but yeah I think we can all agree that we should be very careful with the "Splat" cheating allegations right now. It also obviously is not "skill-based".

The other clips in the video, including the one where I recreate TKO's jump, are without any lag so I think it's probably bad clipping with the death barriers or some other bug.
