Goblin raider punks

Some goblin raiders try to destroy items in a stockpile instead of stealing them. Is this intentional?
(while it is sometimes frustrating, it is also hilarious. And gives us motivation to actually protect our village/buy peace)

Another question. A friend of mine said that when goblins successfully steal your item, they burn it in their campfire. Regardless of what item it is.
Is this true?

Some enemies will try to steal the items and others will try to destroy them.

This was true in the first alphas, it got changed later so they no longer burn stolen items.
