The fastest way to manual the LM after publishing is to turn C2 cut off. Select the tree lines by ‘Buy All’, tap the [-] box next to C2. Then set purchase amount to max. The number of levels of upgrade you can afford will go up by one or two, pause, and then rush up by a lot. After that it will pause again and go up by a few. A few might be from 200 to 220 or 150 to 165. Buy immediately after that little jump. Wait again. Keep doing that until it doesn’t really jump any more. At that point, usually when tau_5 is 90% of peak or so, turn autobuy back on.
