hum i have a bug that happened to me 3 times, and this a really annoying one, to explain,
when i connected to ddnet (from steam) it acted like it was my first time playing (so language + username)
and on ddnet i use a username called "sAsUkEEEEE" but when this bug happen, my username takes the one of my steam account (which is "Rhasanamon"), and i've got like this account data, when the data of the account called "sAsUkEEEE" are wiped out (edited)
