ResourceLoadingException: Resources are still being loaded, please wait!

[MrShard]

Details:
This warning appears right after server startup when a player gets an advancement.
It seems that OutboundToDiscordEvents.onAdvancement() is triggered before the resource manager is ready.

Environment:

Paper 1.21.3

DiscordSRV 1.30.2-SNAPSHOT (build 1425549)

InteractiveChatDiscordSrvAddon 4.3.3.0

InteractiveChat 4.3.3.0

Expected: No warning when sending advancement messages to Discord.
Actual: Warning spam in console if advancement occurs early after startup.

Does it eventually finish loading and work?

I fixed it by clearing the old folder and creating a new one. I can't explain how it helped, but my 2 past issues didn't solve it (3 weeks ago)
