this script is just super old ...
when this script was freshly made version 1.0, 3rd job wasn't even release yet (year 2009)
there is a get-around, by using level range + job restriction, since 3rd job is always level > 99
the sample quest log script was made way back during eathena period,
so rathena should support up 0.3 I guess
version 1.0 and above is just hercules
about the daily quest ... although its custom, but *setquest with adjustable time limit is official
I think rathena will get to it eventually after convert quest_db.txt into YAML format...
