Not sure if this is a bug or merely overlooked.
When equipping any engineer kit, the kit is failing to remember the targeting status it had the last time it was equipped.
To reproduce the issue:-
Equip the elixir gun and set move 1 to autotarget on with ctrl + mouse 2
weapon swap
weapon swap back to the elixir gun.. autotarget is no longer on and needs to be set every single time the swap occurs.
