If the player enters a village with a high bad omen level and is transformed into raid omen, drinking another ominous bottle of lower amplifier will make it display the effect indefinitely (and might also be applied permanently until they die), even after the raid has ended.

How to reproduce

1. Step into a village, then drink an ominous bottle of bad omen V.
2. After that, drink a bottle of bad omen IV.
3. Wait until the raid omen timer ends and the raid starts.
4. Notice how the raid omen effect timer still displays with "00:00" seconds left.
