Is training potion ineffective for last 10 minutes
I have been observing this for quiet a few time. Recent example is that i was training an army with training time 40 minutes. The last 5 minutes of boost were left. So after 5 minutes 20 min training must have finished. In the mean time i did an attack and when returned to my village the training time left was 33 minutes. I have observed it a lot of times since i have started using training potion. So if really want to have full value of your training potion. You must stick around your home base and see your army getting trained otherwise supercell do these cheap tricks and cheats with you.
See if others also observe the same.
