A number of players have been experiencing a strange glitch where the weapon auto-drops after a kill in spike rush. It seems that immediately after making a kill something causes the weapon in hand to instantly drop, leaving you defenceless (as you can see in the clip linked below).
Despite suggestions of misclicks and incorrect auto-binds, other players seem to have confirmed this has been happening since the last patch. A handful of players have reported experiencing this, though we don’t have a large enough sample to say what’s causing it! Have you experienced this too? Let us know!
