This reverts commit 68c6f6671121b1b72b62db97858c25c82f6e834f. I was able to reproduce the issue, in a case when it was definitely NOT a falling_node mishap. Snuffing fire by placing a node against the last bare face of embers apparently creates a race condition, in which the node you place can be removed instead of only fire being removed.
