Need help with getting fuse for TNT barrel.

[RGamerK]

In the workshop, there's supposed to be a cotton string, right? Well, it's not there. All that's there is a 'box of odd string', but I can't pick anything up out of it, next to it, around it, etc.

I've done everything up to blowing up the gun powder keg but now there's nothing else I can do. Is my game broken?
