So far it seems to be every death, relogging fixes for current life. Rebinding and resetting keys does not help. Have not tried default controls. It now happens every match every death tho.
Im having this bug every match on geist, seems to be when i respawn. Always either 1-2-3 they are rebound mostly to mouse buttons but my bomb is on 1 and that stops working aswell. Have no fixes found yet other then rejoining.
