[HOW TO]Fix ele shield mages/priest/oracle skills?

Hi.

I have some bugs like priest/oracle.
If use elemental shield old ele shield must be close automaticaly. But skills are no closes. I can use more and more ele shields. but all shield exists, but working only last shield. How to fix it? To get old shield close automaticaly when uses new ele shield?

Archer/Hunter ele attack buff work fine, but no ele shilelds. Help please.
Thank you.

They are not supposed to overwrite the last elemental skill, they stack, the person using that priest/oracle has to cancle the effect of the last one, because you can even have all four of them on use, which isn't recommended obviously, this priest/oracle skills are not like the archer/hunter buffs

OS shaiya closed old shield if use new shield, so its a bug. And i want to fix it =.=.

Then just compare how the archer/hunter ele buffs work with those priest/oracle buffs, by comparing them you will be able to notice how is that archer/hunter buffs overwrite the last buff and by knowing that it won't be too hard to fix the priest/oracle buffs, that is the way in which all this kind of "bugs" are fixed, by comparing first and then fixing the differences

No its not so easy, archer buffs and mage buffs ele have are same values absolutely right without TypeDetail, so archer 94, mage 95, so 94 - ele attack, 95 - ele shield, all other values are absolutely same. Need other idea =.=

Do it thru ps_game, When activating one skill check if other is activated if it is then prevent it from executing.
