.1 Devs can andwer that.
.2 That has to do with Iv itself, if you add high-poly models to the game it tends to do that, you can get certain "taxi bug" fixes on here or on GPM.
.3 That has to do with the keybinds of ELS. I believe that if you change all your keybinds to something like Ctrl + G, J, etc. It solves it.
Hope it helps.
