Really enjoying the game so far. One bug I noticed is that completion times do not update when you increase workers in the middle of the job completing. So if you hit go on a job with no workers that takes 1 min then max out it's workers the current run will still take 1 min to complete. This also causes the $/s to not update so you can't tell how much of an impact the workers are having unless you wait until nothing is running.
Also the reverse is true. If you start a job with max workers then remove workers the time doesn't increase. The biggest problem with this is that it could be exploited. Give a long running job every worker you have, start the job, move the workers to other jobs.
