sapper backstab glitch.

[Faptain Hook]

I've ran into this issue when backstabbing. For some reason when im right behind an enemy my backstab will be primened but often times instead of dealing the kill he switches to the sapper tool. It's happened way too many times for me to count. Maybe im dumb and the oppenent has a particular item equipped, but i know a razorback equipped when i see one.

Any chance you're hitting "q" or mouse wheel as you go? Do you have some spy scripts installed?

Also the above happens when you are wielding Spy-cicle and you get hit by fire.
