When planting the HE charge as a Soldier, occasionally (I’ve had it happen 2x) the charge is set, but your weapons are no longer available. You are stuck looking at the extended arms with the HE plant animation. In this bug you can’t switch weapons, melee, or shoot.
I’ve suffered 2 frustrating deaths as a result of this bug. Obviously you can’t defend the objective… I hope Splash Damage can look into this and fix this glitch.
