Monsters stop dropping items/meso & attacks not working properly

Anyone else have any suggestion? I don't know of a mob which has the ID of all 0s so I don't think that is a file I should be adding (especially since no other source I have found has 0000000.img

Well your items not dropping issue is probably not related to the TakeDamageHandler exception.
The TakeDamageHandler exception is probably due to faulty/outdated packet reading resulting in a mobid of 0 in some cases.. Look at specific cases for the 0 id and update the packet handling to get rid of the problem.

For your items not dropping problem, well it's definitely related to some type of ConcurrentModificationException, not necessarily in MapleMap (but probably).
I remember that monsters not spawning was related to either bad threadsafing in MapleMap or sometimes because of the Steal skill.. Items not dropping is probably similar, you might want to refactor the MapleMap from localms v88 or something, because that one probably has better threadsafety than your current one, but I don't know if it is actually 100% threadsafe.
Also look at the spawning thread because that has threadsafety issues too..
Anyway these problems require a decent amount of knowledge in concurrency and threadsafety, but are usually easy fixes once you know what's happening.

dude that's not the fix LOL

I am pretty sure the mob 0000000 .xml problem occurs during Carnival Party Quest and does not affect the gameplay. So don't think it is related to the mob spawn/drops problem.

have someone managed to fix this ?
