Statistics stuck on loading (1.13)

Cannot confirm. Does this happen in every world?

That happens on servers.

After having this issue please add the file [.minecraft/launcher_log.txt|http://hopper.minecraft.net/help/guides/finding-minecraft-data-folder/] to this ticket.

Done 🙂 

Uhm, that's a log file of only startup of launcher, there is no start of Minecraft .

Didn't mean how you entered the statistics, but when. Wanted to see if in the log file was anything logged after that.

Oh okay. 

Clock: 7:27 PM

New log file is submitted!

As before you connected to that server?

Yes, it is 🙂 

Is that still an issue for you in 1.13.1?
