[BUG] Fire tag not functioning

[Audidemi]

Describe the bug Fire data does not seem to be working on the player. This command:

execute at @e[tag=Flamering] run data merge entity @e[limit=1,sort=random,distance=..3,tag=!P] {Fire:10s}

Works perfectly on other entities in the area I intend to affect, but the player itself does not get affected.

To Reproduce Steps to reproduce the behavior:

1. Run this command in a command block after spawning any entity with the tag "Flamering": execute at @e[tag=Flamering] run data merge entity @e[limit=1,sort=random,distance=..3,tag=!P] {Fire:10s}

An additional, simpler method. Data merge entity @s {Fire:377s}

Expected behavior Player should be on fire, showing the burning animation and taking damage (in survival/adventure).

Minecraft setup

• Minecraft version: [e.g. 1.21.1]
• Fabric loader: [e.g. 0.16.5]
• Modify Player Data version: [0.2.2-1.21.1]
• Other mods/versions: [
  • Java 22
    • modernfix 5.19.3+mc1.21.1
    • modifyplayerdata 0.2.2-1.21.1
    • smoothchunk 1.21-3.6
    • worldedit 7.3.6+6892-3d660b8 ]

Logs Game did not crash. Command/command block produced no output.

Additional context Thank you!

Hi, does the player appear on fire for a short time (~0.5s) when running the command, or is it not set on fire at all? Did you verify longer times (/data merge entity @s {Fire:300s}) also don't work?

Interestingly, at first visually nothing showed up. After restarting the world, the fire animation did start showing up, but still did no damage to the player. It’s very inconsistent, sometimes when a server is joined the animation will show up every time during that session, but other times not at all. Still no damage either way.

Are there any command blocks that change the Fire tag? Can you reproduce this with the same mods in a new world?
