So, i made gravity boots,whoopie!Though I was flying with it on,then unequiped them and fell to my death. Respawned put them away and equiped my regular boots and began to fly. though i couldn't control it. I just flew upwards until i plummeted to my doom.

Restarting the game seems to

Priority: -> normal
State: -> new
Client: -> Block Story

Restarting the game seems to fix it.
