I think not being able to sell string is kind of unfair. For beginners to start out with low tier spawners like zombie, spider, skeleton the drops aren't very profitable. And we aren't able to sell string which is a main drop from spiders! I have loads of string and nothing to do with it unless I want to sell it for 0$. Please take this into consideration for all the new players.
I think this is a very good idea, even if only sold for like $25-50 per stack, would be better than nothing.
That's exactly what I'm hinting at. It doesn't seem right just deleting stacks of hard grinded loot. Hopefully something changes
Follow up to my original post! Okay so recently I have discovered you can put 4 pieces of string in a square formation in crafting table and turn it into wool. Wool sells for quite a bit so if you have a bit of string it's pretty rewarding!
