ViaFabric button disappears permanently after toggling off/on

[AntonioBrazilian]

Bug Description

When I disable the ViaFabric button in the mod settings, it hides correctly. However, after enabling it again, the button does not reappear in the Multiplayer server list screen. Even after restarting Minecraft, the button is still missing. No crash or error occurs — it seems to be a UI issue where the button is not recreated after toggling the option

Steps to Reproduce

Steps to Reproduce:

1. Launch Minecraft 1.21.11 with Fabric Loader 0.18.4
2. Install ViaFabric-0.4.21+138-1.14-1.21.jar
3. Open the Multiplayer server list screen
4. Open ViaFabric settings
5. Disable the on-screen button
6. Return to the server list (button disappears correctly)
7. Enable the button again
8. Return to the server list

Result:
The button does not reappear.

Expected behavior:
The button should immediately show again after being enabled.

Can you check the config file to see if the value has changed or not? If it didn't then i might assume it as an NPE.

@Kichura

I already checked the config file The value changes correctly when toggling the option (false/true), but the button still does not appear in the Multiplayer screen. No errors or crashes. So it seems to be a UI issue.

Restart your client if possible, will go test it myself meanwhile.

@Kichura Also, just to clarify: this is not a serious or game-breaking issue. The mod works normally otherwise. I just wanted to report it so you are aware and can fix it when you have time.

Tested it by manually editing the config file and cannot reproduce, but on mod menu; i can until client is restarted so will confirm.

Got it, thanks for testing. Yes, I'm toggling the option through the mod menu only, not editing the config manually. The issue happens every time for me.

@Kichura Thanks for confirming the bug and taking a look at it!
