Function for items on hand(s) do not work after dismounting boat

What I expected to happen was
The item(s) on the player's hand(s) were suppose to be present.

What happened was...:
The item(s) never appeared and attacking, building and/or defending was useless until death or resetting game.

Steps to reproduce
1) Make boat.
2) Get any item and have them on hand.
3) Jump in boat.
4) Move boat.
5) Dismount boat while it's moving.
6) Notice that you can't place, block, or attack. It should match the attachment shown.
