So this is the first time this occured for me today. I was playing hardcore SnD on express today when i was the last person. I got the bomb and proceeded to plant on the outside bomb stack by the train. Except everytime I press n held X it make the bomb opening sound and wouldn't plant. I tried about 10 times there before having to make a run to B bomb where I ended up dieing. I did pick up a weapon no problem so it wasn't a controller issue however all my team mates in our party did watch this occur. It only happened that one round of the game. Any ideas to why this occured?
