C6 Event drop list

[ver]

Hello,

I have a problem with droplist which I can't investigate...

I've been using L2Day event with changed drop chance to close to 90%. All works fine without any errors. After like 20..24hours some letters stops to drop. Simply - they are not dropping from killed mob, while others letters are dropping without any problem. In a same time some quests (for example the one for fishing shots) are "hanged" and players can't take'em. Ofcourse without any error - just quest window dissapears.
I've checked all logs - nothings there. All as usual. Players can login, can play, no lags, no hangs/freezes, drops works fine except those few (not all, just a few) letters.

Any idea where to search? How to investigate it? After restart all works smooth again...

Best regards!

schedule your server to perform a restart every 12 hours. I have it that way and no problems.

Well... yea, that is some kind of "solution", but I'd more like to fix it somehow

Additional info - raidboss minions had double spawns after killing'em while this "thing" was in effect.
