The same, as well.

[dirkf]

The problem has been solved here but I'll let the commit close this issue.

[stephen-czetty]

I have the latest code from the repo, and I'm still getting the error for player 13400486c'

[GregoriusT]

I think what was meant was "once the issue is solved, it will close this issue as well" implying it is not solved yet. (which yes it is still broken for me, which is no wonder since the repo hasnt been updated yet)

[dirkf]

If you're desperate, apply the linked patch.

[stephen-czetty]

Sorry, I misunderstood. You linked to a closed issue, so I assumed that meant the patch had been applied. The patch you linked to does work fine, after manually applying it.

[dirkf]

A nightly build with the fix should appear in the next few hours.
