Physics collision on Landscape "edges" in 4.27 is not gonna be fixed?

Hey, so I thought it was just the Advanced Vehicle Plugin that had problem with landscape and discovered after test with physics-x, custom made with static meshes and , custom one with skeletal meshes that the same bumping is happening when you get a little a speed on things, this is incredible annoying. tried a lot of different settings and this kinda ruin 2 games I am into Developing on.
So I just want a clear answear really is this gonna be fixed? and if so when? One of the games should be released on SteamFest in October so this is kinda why I am asking
