The bug consist of a problem with the animation of the Bow and the Trident.

When facing to a block (may be a wall or the floor) the animation behaves weird making a mining like movement before actually loading the weapon, *similar to the effect of mining fatigue.

This can be very annoying in PvP and PvE because it takes longer for the bow animation to actually start.

To recreate the bug, you need to stand near a wall or seeing the floor with the weapon equipped (preferably with arrows in the inventory if using the bow), then do a tap, a short-tap in the screen or charge completely the weapon and you will see that it makes a weird slow animation.

This weapons alredy had a similar animation but was much much faster and shorter.

What I expected to happen was:

The Bow and Trident to shoot normally.

What happened was:

That both weapons made a slow animation before actually charging and shooting.
