Impaling a In the Middle of Pushing A Footswitch Elevator Potentially Dangerous?

In my map i lose control of my character rarely and i think that it might have something to do with this but i am not sure.

I have these traps with footswitches.. regions are layed out over them equal in size to the step.. when the unit steps in this region the footswitch associated with it is killed and the unit that stepped on it is immediately impaled..

Since the switch is an elevator and it is impaled the moment the switch is going down by dying.. can sending the unit into the air with impale at the very same time be the cause of my char sometimes randomly losing control?

The control isn't lost the moment of the trap.. it's like once it happens the unit is no longer acts like a regular unit randomly.. something seems tainted about him

it could very well be something entirely different causing since i cannot see it instantly happen at the moment of one of these traps going off but it's the only fishy thing i can come up with.

I have noticed problems in the past with having units unhide on an elevator with their rings being messed up.. and impale either does something with hiding/unhiding a unit or it elevates the unit.. i am unsure.

Perhaps post your trigger?
