"regentype" argument in mob spawn

[Euphy]

Aegis includes "respawn type" as the last argument in its monster spawn:

declare putmob snnnnnnnnn? ENUM++ // ["spawn map"] [centroid x],[y] [coordinate range x],[y] [number spawned] [monster id], [respawn time min], [respawn time max], [respawn type]

We've carried the values over into our mob spawns, even though our field currently doubles as an event field:

anthell01,0,0,0,0    monster    Maya Purple    1289,1,7200000,3600000,1

"0" is the usual value, but does "1" have any meaning?

If it's important, 'regentype' should be separated from the 'event' field. This would create one more optional argument, making permanent monster spawns look like:

map,x1,y1,x2,y2    monster    "name,lv"    id,amount,min_regen,max_regen,eventname,size,ai

sscanf(w4, "%d,%d,%u,%u,%127,%d,%d,%d[^\t\r\n]", &class_, &num, &mob.delay1, &mob.delay2, mob.regentype, mob.eventname, mob.size, mob.ai ) < 2 )
