Unfortunately, I don't have words to describe worker order assignment and pathfinding in the current (patch2) version of Per Aspera other than "bad". You don't have to build a large base to run into these issues. Here are a couple I've run into almost immediately (hard difficulty). Early game base after the first colonists arrive, about 7 worker hubs. One of the workers keeps carrying steel back and forth between iron mine and steel factory right next to each other in an endless loop, not doing any useful work whatsoever. Fresh restart, building first mines and factories leading up to the drone factory. The only worker is carrying iron to the steel factory using a roudabout road that was historically built first (via a powerplant, another mine and the landing module) not via the much shorter road that was connected later. I enjoy the challenge of building efficient layouts just as much as I enjoy the premise and the plot of the game. When the game is challenging not due my choices, but due to programming, it quickly kills any motivation to proceeed. I hope pathfinding is improved in upcoming patches at least to the level where the issues are at least not base-breaking, and looking forward to give the game another go in a month or two.
