[Costume any equipment]

There is a bug here where the item effect still stays in effect after converting into a costume. So, players can exploit this of having double headgear effects.

[Player's Equipment and Status is not being updated]

The player's equipment bonuses are not being updated and sometimes being a permanent status instead.
It never happens consistently but it happens randomly.

I believe the concerned file is clif.cpp but I have already applied the fixes that were stated from the rAthena's Github issue tracker but the problem still persists.
I have already disabled PACKET_OBFUSCATION.
