Happend once to me today. So I repeated it to check, if it happens everytime (at least to me).
Getting a disconnect during a PvP-ground match lets you log on again in the instance, but you can no longer attack enemies with ranged weapons. Only with the third, the riflebutt/palm attack. Also everyone appears as a green/blue dot on the minimap with their names equally being blue/green. You can be attacked and killed though.
Death and resurrect does not fix it, swapping and unequipping the weapon neither.
