So, I'm not sure if the error is being caused by Jr. Wraiths or Neckies; however, a few years back when I had a server, a common problem with pointer errors was actually just an invalid item ID being dropped from a mob. When we (my wife and I) would try to relog to the channel that we were just booted from, it just boots us with the same invalid pointer prompt. Fixing the drop table (could be a quest drop that we can't see), or rearranging some packets should do the trick. Thank you!
Your files are probably out dated http://royals.ms/forum/threads/patch-22-11-15.44611/ The special pie mobs spawn after you kill normal mobs and if your files are outdated you crash when they come out. Well you are right the invalid item being the mob
