As described above, Capitalized UUID in resource pack causes gophertunnel to panic.

Error:

2022/08/07 23:52:05 error: texture pack {uuid=3BBD640E-B454-4358-BB57-33C49C0DFCF5, version=0.0.1} not downloaded
panic: dial minecraft 127.0.0.1:62488->127.0.0.1:19132: use of closed network connection

goroutine 1 [running]:
main.ExampleDial()

main.main()
        D:/D-Backups/Go/Gophertunnel/main.go:108 +0x17
exit status 2

Tested with PM4 and confirmed by just changing the case of the resource pack UUID. (not entire UUID) manifest.zip (Capitalized UUID)

manifest.zip (Non-Capitalized UUID)

That's... peculiar. I wonder if this is actually a PocketMine issue where the client just doesn't care. Gophertunnel shouldn't really care about the casing as long as it's consistent throughout the login sequence. Maybe pocketmine lowercases it in some places but not in others.

Did you test if gophertunnel could properly connect with the lowercase UUIDs?

Yes, I tested it with fresh PocketMine with no plugins it works fine when resource pack contains lowercase UUIDs.
