That Lodestone was on top of the Furnace, but it then disappeared. I thought it would be in my inventory if I had mined it. I look in my inventory and see one. That the old Lodestone! But I take my compass from the chest to see if it turns like crazy. But it still points to the old position of the lodestone even though it was destroyed before.

Step to Reproduce:

1. Place a Lodestone
2. Create a Lodestone Compass
3. Press Esc, resume the game, then quickly mine the Lodestone
Observed Result:
Even when the Lodestone is destroyed, the Lodestone Compass still points to that Lodestone's old position
Expected Result:
 The Lodestone Compass spin randomly.
