Some slight Abusable bugs I've discovered.

Reload and looting at the same time bug -

So they recently added the ability to open doors while reloading, this changed a few things, your reload stops while you open a door, or when you loot and reload at the same time However! if you simply right click on the loot on the ground (Through TAB = Just as fast as drag), you may reload AND loot at the same time. Does not work with Drag/F looting.

Windows + Crouch Jump bug -

Windows are actually irrelevant in this game, if you are able to crouch jump, you may crouch jump in and out of any widow Broken or not, seriously, jumping through a non broken window is the most rediculous thing and it makes you super stealthy while defending a building if you decide to window jump, I used to punch them out myself until I learnt about this.

Suprisingly not commonly known Motorbike "Bug"?

While driving a motorbike, you can go full speed and ram a building to jump out of the bike asap and take... ABSOLUTELY no damage compared to a 4 Wheeler, works with trike too.
