Light skip destorys objects if multi-objects lie in a cell

[hamiguazzz]

Here is another bug about light skip like #23.
If there are not only one object such as animals exists in a cell contained in range of light skip, using light skip will destory some objects in the range randomly. For global light skip, a message of pots destoryed will be given at the same time.

The log reported an error.
