traderoutes are a little frustrating as they are right now. Im trying to gather some supplies with the trade route and am not finding it possible. route to the forge to gather tools and then go to my base and drop them off. then go to pick up some h2 and drop it off at my base. since there are a max of 4 sites to the trade route and no duplicates that is not possible. unload also does not seem to work to unload supplies to my comples.
