You might wonder where the name ExD is coming from. So do I :D
The string "ExD" only appears in that error message when grepping the log of the whole server runtime

$ strings vanilla_tem_2021-03-19_21-11-02.log | grep -iE 'ExD'
say "[ERROR] untracked namechange from 'Ocelot' to 'ExD'"

Sadly the teeworlds log seems to be gone so there is only the TEM log left. Which did not print the latest message that likley includes the "ExD" line.

Yes of course it does. So what happend is that "Ocelot" with the id 6 left. And when "ExD" joined he got the id 6 assigned but then it crashed because "Ocelot" already has this id. But the latest occurrence of "Ocelot" in the logs is a proper disconnect message that should have deleted the player.

$ strings vanilla_tem_2021-03-19_21-11-02.log | grep -iEC 1 '(Ocelot|ExD)' | tail -n 9
