[BY DESIGN] [GTW] Daily tasks can't always be completed in Scientist Career
Many times when work tasks come up that can not be completed. You will be told to upgrade an item that has already been upgraded as much as it can be and you must mind control a tourist. Tourists do not show up every day and many times there is only one of them. Today I have three tasks that I can not complete. Mind control three tourists and there are none and upgrade my satellite dish and wormhole generator and both have nothing to upgrade because it has already been done. Since three items are there that I can not complete, I can not finish my work day doing all the assigned tasks because I can't get rid of the three that are there without completing at least one of them. This will in turn hurt my work performance.
Just as a workaround, did you try building another wormhole generator or satellite dish ?

Also there's a similar one in the doctor career in lower levels where you need to greet a patient which is hard to do if you already know everyone.
