I'll be honest, I didn't know this was a thing until literally just now which is why I'm sharing just in-case others are unaware. If you are planting the spike and have your knife out, instead of stopping to equip your weapon and then rest...

I tried to defuse in custom game and the range and was unable to drop my guns without canceling the defuse. There doesn't seem to be any mention of a change to that mechanic in recent patch notes but maybe I missed it.

I've been in a team for a pretty long time now, and just found out that they will drop me...Now i just feel disheartened and don't know how to react.
