Hi,
after updating from 2.2.0 to 2.4.0 I got this StackTrace:

What happens if you temporarily remove the a5195dc0-22cb-4a5b-a1b2-62d767c7700e.json file from the stats directory?

[John-H-Smith]

Then the UID is removed from the list above but a new one is shown there.
Also I should mention I set player_statistic to false in the config.

@John-H-Smith Could you try the latest version v2.4.1?

[sladkoff]

ℹ️ This is probably a duplicate of #75.

[John-H-Smith]

Oh lol - I thought I was running on the latest version. Fixed!
