[v62] Monsters randomly not dropping mesos/items & Some attacks stop working

[hxxp]

So I have this problem in my server where after a couple of hours, or sometimes not at all, monsters will start randomly not dropping items and mesos. Shortly after, players will start to get stuck at the character select screen and not be able to log back on. Sometimes, attacks such as Genesis will stop doing damage to the monsters as well. I've read this thread http://forum.ragezone.com/f566/monst...s-meso-937735/ and it seems like I have the exact same problem as the OT. The problem seems to lie with a ConcurrentModificationException that is happening however at my current coding level, I'm not able to find the problem and fix it. It would be great if someone could guide to what I can do, or I am also willing to pay a more experienced coder to fix the problem for me if they know exactly what to do. Please PM me if you'd like to go that route. Thanks for everyone's time.

I suggest debugging your server when this issue occurs to see what exactly throws this exception and looking at the stack trace for more information. We can't just simply tell you the answer without any detail.
