Yeah it's not very clear at the moment what to do. It should do what's inside the yellow Repeat container until the Storage you've selected is full. Have you selected a Storage? (do this by clicking the small round button left of "Until Storage full")
I have everything in the repeat box and I have clicked a storage. I thought maybe forever command was messing it up but it still won't work. So this is how I have my bot set up who collects logs and puts them in storage : repeat until storage is full (all commands are in the yellow area) Find nearest log, move to log, pick up log, move to general storage, and add to storage. I also tried having him pick up logs until hands were full and in separate repeat box until storage is full . Everything works just fine until it gets to the add to storage part, also using it the old way of just adding to storage works.
