Is your logistics network too big and you want to downsize? or do you want to upgrade all your bots, but its too hard to get them all to come home?
Well mine was and I did, so I made this mod.

It creates a new research unlocked after logistics systems and space packs that unlocks a Bot Return Port. It has 2 settings, one to call logistics bots, one to call construction bots, and you can set how many it calls at once (Default 500, max 10,000, I recommend 10,000 if you want all bots reclaimed).
