If you've ever called foul at being killed - or killing another player - in Team Fortress 2, your screams of rage may have actually been justified.
Reported by Nicknine - a member of the TF2 Classic development team - a 10-year old bug tied to player hitboxes has just been squashed by Valve.
The issue in question boiled down to certain class animations becoming scrambled within the game's code - meaning hitboxes were not properly reflecting through the animations of certain classes once some very particular - yet easily triggerable - conditions were met. This, in all, could sometimes result in a hitbox representative of one animation applying to other; meaning limbs would get hit or dodge attacks without actually being there.

Though it's much easier to understand the effects through the video down below, Reddit user 'Sigsegv' explains it well enough. Essentially, switching from a few particular class choices to another select few would cause the X-Y axis of the current player model to become desynced with the server. In their words: "if you joined a server and your first class chosen was soldier/pyro/demo/engie/medic/spy, then any time later on that server when you were scout/heavy/sniper, your server-side animations would be screwed up."
Easy enough, right? The same applied to MvM matches considering the spawning robots work in a similar fashion. After 10 years, we can consider Team Fortress 2 a viable competitive game.
