Configuring Gold Medal (eventitembag6)

PLEASE NOTE THAT I NO LONGER NEED TO RESOLVE THIS!
I do not know how to go on about fixing this, but I no longer need the BoKs to be dropped from Gold Medals, I found an alternative to fulfil my needs :-)

Hello everyone!

What seems like a simple task turns out to be quite challenging!

What I want:
I want Gold Medal to drop BoK+1, +2, +3, +4 and +5.

What I did:
I added BoK+1, +2, +3, +4 and +5 as drops to eventitembag.txt

What's the result:
Medal drops BoK+3/4/5 and some strange unusable "Lucky puoches".


As an attempt to investigate I cleaned the eventitembag6.txt and included a drop for BoK+1 only.

The result:
Gold Medal drops BoK+1, +2 and +3.


Someone must have encountered this before.

Any help will be much appreciated.

Thanks,
Avest

Still waiting for someone to chip in their thoughts :S

As a little update:
In Eventitembag6.txt I now have BoK+1, BoK+2, BoK+3.
This configuration somehow seems to be dropping all 5 BoKs. However, BoK+2 and BoK+4 have a significantly greater chance of being dropped than the remaining BoKs...

In fact I have done a little testing to see the percentages and have found that with this config the drop chances are approximately:
BoK+1 8%
BoK+2 32%
BoK+3 16%
BoK+4 32%
BoK+5 12%
My assumption is that EventItemBag6 has a chance to drop an item of level of +0 to +2, but I can't really figure out why the above percentages hold. It'd be great to know where to chance the min/max level of EventItemBag6.
Anyone? :-P
