1941565808reported this bug
I wrote a test item:
1. onSwing deals 2 damage to myself, and the damage carries the fire damage tag
2. While holding the item, if I take damage tagged with fire, will receive a message
3. onUse grants an Aura with an onDamaged component; while the Aura is active, any damage that does NOT carry the fire tag should trigger a title message
However, the test results tell me that the onDamaged component did not successfully recognize the damagetag condition, because while the Aura was active, taking fire-tagged damage to myself still triggered the title message.
