If the flags are stored as global integers, why are the flags stored in the itemtypes as Strings? Did you ever wonder that?

To me this looks like an exporting mistake.

Did someone ever try to remove the quotation marks? From this:

flags        = "FLAG_HASHAIR + FLAG_HASBLINKANIM + FLAG_HASSOUND + FLAG_HASPREVIEWIMAGE + FLAG_NO_ANIM_OPTIMIZATION",

To this:

flags        = FLAG_HASHAIR + FLAG_HASBLINKANIM + FLAG_HASSOUND + FLAG_HASPREVIEWIMAGE + FLAG_NO_ANIM_OPTIMIZATION,

?

What happens?
