Amazing experiment!
Sorry for not used to this discussion board, missed last page of this post. !!-_-
We found that there were still tons of bugs about the storage boxes, which had not been coverd by our test. We will fix it soon.
As you mentioned, feathers can not be put into the storage box, that's a bug, obviously.
A throw-away button had been added into game in dev-version. You can throw anything away into sea via this command.
Bows and arrows are useless in ver. 0.3.7 and earlier. But weapons like these two will become an important role in the next update.
