I would have to say that this is the worse bonus out there.
I have managed to avoid it in the past, by choosing not to complete certain challenges, but now you snuck it into war rewards. I would have sat last war out just to avoid this BS reward.
I have spend a long time upgrading my 24-48hr buildings, and am able to collect them at a convenient time. But now this upgrade has them collecting at random times, that are always changing. With all these LTB it is important to be able to collect the maximum from our buildings. that's why we built and upgraded them.
I have lived with all the other Gree BS, but this could be the bonus that causes me to retire from KA.
Please allow us to be able to remove unwanted bonuses, or please remove it from my account.
