Question Does this needs fixing ??

My test har died fighting a mob. And then it writes this

If it needs fixing, what do I do ?

It doesn't really need fixing; it just means that the code tried to register the player on logon, succeeded and now tries again after a death.

I can't seem to find that message in stock code, by the way.

dg_scripts.c:      log ("Add_to_lookup failed. Already there. (uid = %ld)", uid);
