i haven't seen any tf prevent me from using a medkit, odd. the white wolf one just let me use normal medkit, and doesn't seem to have any odd effect overtime.
only thing i seen that had hypno was the pig, but it was short lived because i got stuck trough the wall... also the ball that teleport you to the conveyor need to be made smaller to allow dodging, and with a shorter hitbox (it genuinely un-avoidable, making me require to spend bullets on them just to try other tf or interactions).

It's not TF, it's the horny/drone state that prevents it. It's triggered per form differently. You can temporarily use animation speed up to overcome this bug, just use interaction key 5 or "b". The servitor is purposefully large. If you really don't want to spend ammo you can lure them into a loop.
