Suggestion / Bug Platform

When playing Party Games on the Hypixel server using LabyMod 1.8.9, I noticed that the bossbar or the text displayed above it sometimes fails to update correctly. For example, during minigames where the bossbar is used to display a timer or other information, the text either freezes or updates with a noticeable delay. This issue does not occur on newer versions of Minecraft (tested on 1.21 and 1.21.4).

Steps to Reproduce:

1. Launch LabyMod in version 1.8.9
2. Join the Hypixel server
3. Start a round of Party Games
4. Observe the bossbar during minigames.
5. Notice how the text doesn't update or gets stuck.

Expected Result:
The bossbar and its text should update in real-time, just like on newer versions.

Actual Result:
The bossbar sometimes does not update or only updates after a delay.
