By coincidence I went back to [rev=13497], where Zephyrus pointed out that there is one mob spawn that will never spawn, and will keep retrying every 5 seconds.

npc/mobs/fields/prontera.txt
[code]prt_fild06,222,30,40,10 monster Green Plant 1080,15,900000,450000,1[/code]

Note that the whole area is [i]deep in the nonwalkable ocean part of the map[/i], so the spawn line is messed up beyond repair... unless there's a typo and the whole thing should have been shifted 100 squares upwards.
