2013-08-22 00:25:24 <willee> hi. i got little trouble today starting illia
2013-08-22 00:26:41 <willee> we tried to simultaneously start it and when i had to type comrades names they were already chosen
2013-08-22 00:26:43 <Frostypants> hm. You typed '0' as the first name?
2013-08-22 00:26:47 <willee> nope
2013-08-22 00:26:48 <Frostypants> oh, yikes
2013-08-22 00:27:57 <willee> first time i canceled. second time i checked two names of required persons and they were already on list again
2013-08-22 00:28:43 <willee> then i typed third player - not who tried to start it same time as me - and quest began
2013-08-22 00:29:51 <Frostypants> two people talked to Valia at one time?
2013-08-22 00:30:11 <willee> and if i remember correctly error message when i first tried to type comrade name was not like mes "You can't name yourself.";
2013-08-22 00:30:28 <willee> but mes "You can't name yourself or someone already chosen.";
2013-08-22 00:30:34 <willee> yeah
