The difference in item chests

does anybody have an idea why the item chests in VF4 (not evo) differ from each other?

 

I dont think there is any difference.Can you give me some examples

 

Hasn't there be a similar thread that you started lately?

 

Yes, Zss, i have, but i couldn't find it back, not even with search, and i realized that i posted it on the wrong section (it would probably be possible, but i'm new to the site)

 

and, anton, for your examples.

I mean that there are 2 types of chests, a big old treasure chest-like one, and one that looks like a smalller case
