Until today flame enchantment on bow worked fine.

What I expected to happen was...:
Fire an arrow with bow having flame enchantment. Arrow on fire, monster  on fire, recover flaming arrows that missed monster.

What actually happened was...:
Arrow not on fire, no fire effect on monster, missed arrow not on fire. Tried dropping bow, picking up again, etc. Saved game, restored  game  - no change.

New  update -  Started new world.  New character now has bow with flame and  Power  3. When interact with skeletons, every other arrow causes enchantment to work or not work. Aiming arrow  at ground has same alternating effect.

Steps to Reproduce:
1. Put a step by step guide on how to trigger the bug here
2. Have  bow in hand, arrows in pack..
3. Pull bow  back, aim at monster.

4. Release arrow - normal routine.  As if  enchantment gone, but examine bow still lists flame  enchantment.
