So much bugs with this game

This game has a bug that has been here for a LONG TIME, I decide to come back to this game after a break. The first game mode I play is HMX, after a minute of playing someone is already using a glitch which allways them to go through walls, one time me and my team were hiding in this spot, this person got all of us at once by using some type of glitch, I was live streaming it at the time

This bug isn't even new and this is one of the reason why I stopped playing this game for a while.
