Vehicle handling..

Hi yes i was afraid that may be the case. I am not always great at explaining my problem. I do have another project that uses raycasts and physics to move it around that feels great to control .I have been creating random small games in order to learn the unreal engine a bit better since…I kinda suck .Hence i am trying to figure this out .I have just noticed however that i may have found a bug. It appears that my changes were taking effect but i have to delete the car and re-add into the level .I have been compiling and saving every time however it seems to not take on the new values until i delete the car and then put it back into the scene . Is this normal?? It is incredibly frustrating as it is intermittent and sometimes(RARELY) the value changes work fine and others i have to delete and re-add. So i never know if my changes are working or if i have to do that process .
