trophy quest irregularity

[Ssajit]

i have been doing some lava golem materia quests at trophy hunter in kira. all other trophies lvl 75-80 give 61400xp but lava golem materia gives 41600xp. is it intentional or something else?

fire beetles after doing the quest more than 5 times:
[09/26/07 08:34:22] You have received a new quest - 'Go Bag 5 Fire Beetle Compound Eyes'.
[09/26/07 08:34:25] Gained Berserker experience: 30700 ( Quest Reward )
[09/26/07 08:34:25] You have received 4 silver 300 copper.

lava golem materia less than 5 repeats of the quest:
[09/26/07 08:34:39] You have received a new quest - 'Go Bag 5 Lava Golem Materia'.
[09/26/07 08:34:41] Gained Berserker experience: 41600 ( Quest Reward )
[09/26/07 08:34:41] You have received 3 silver 200 copper.

Part of me suspects that's intentional due to the absurd number of trophies (and comps) you can get from the lava golems in a relatively short period of time. Hopefully, they'll fix that and bring them in line with the other trophy drops.
