[Crash] AoE/Multi-hit dmg skills

[Bia10]

Well it turn out that i was slightly wrong, its not that the MapObject/MapObjectLife system is entirely broken. Its only when damage skills dealing AoE or multi-hits interact with mapObjects then the system eventually bogs down in overflows.

Furthermore it seems to be related to second main point of current instability and that is concerned with problem that some items cannot be properly removed. (at this moment its unclear if single target single hit skills cannot produce such buggy items, will test soon)

Well any idea where should i look to fix that?
