Mobowner almost crashes the game when mob has an invalid UUID

Title kinda explains it all. Somehow the game goes to literal seconds per frame upon rendering a mob with invalid UUID with "mobowner" enabled. Normal nametags work fine. Future nametags work fine.
Disabling the mobowner thing instantly fixes it.

can you send any errors in your log? (enable show logs in the minecraft launcher)

Sorry for the late response, had to fly back. It throws a ton of the "response null" messages. Then a probably interesting bit. And then a ton of response null again. About 6 a second.

I can +1 on this one as it happened to me today.

There is a test server I use for testing different mods and I had a couple donkeys I tamed on a cracked (offline) account which basically set the mob's owner to a nonexistent account.

The following error was spammed into the console: [Lambda]: Response is null or blank, internet might be down and if I leave it go, Mojang eventually rate-limits me.

A suggested fix is to recognize cracked/offline accounts and stop the request loop to prevent the game from freezing up and/or Mojang from rate-limiting you from their APIs.
