Replicate by making the following program:
while true do turtle.turnLeft() end

Now, run the program.
When right clicking the turtle, it updates what the model should look like, and plays the respective animations.

Is fixed? :~

this also seems to be the same for doing the equip/unequip programs where the items don't render on the turtle until you right click (although i think if you make the turtle move in a direction not just turn, it will also update the model and make it render).

This seems to be the same behavior observed in #113 and #111. Right-clicking seems to be another method to force an update.

Same as #113
