Hello, using squaremap-paper-mc26.1.2-1.3.13, paper 26.1.2 build 63, every time the stats plugin goes to update, console is hit with this error:

java.lang.NullPointerException: Cannot invoke "de.pdinklag.mcstats.Player.getUuid()" because "player" is null

Not sure what the cause may be other than some update breaking it - everything was working until we updated the server. Restarts didn't fix it either.

Thanks!
