Unable to manually block with only melee equipped as client

[doomsdayforte]

How to trigger:  Equip only a melee weapon and join another player's session as a client.  Manual blocking does not work but automatic blocking from before still seems to happen. 

Temporary solution:  Hold your Weapon Swap key to 'equip' your melee and manual blocking is restored. 

Hosting a game or playing solo allows you to block without holding Weapon Swap.
