I do the same thing as Konijntje indicated. That said, since I stumbled on the issue, I’ve been more careful at planning my TC use. I queue up just enough work to take me to a time period when I know I will likely get to have some time to play, and I anticipate if it will be a time that I want to take the opportunity to change direction. (change color of heroes to train, or start a camp upgrade or a research).
It has worked nicely for me thus far… I hardly ever reduce the training queues anymore.
What I’d like to be able to do is queue up jobs of different types ahead of time in a given camp. ie. If I have queued training for 5 green heroes and I got an influx of recruits I want to use, I’d like to be able to say add the training for 4 red heroes. I don’t care it the red heroes training doesn’t start until the green heroes training is completed, I just don’t want to have to wait until they are done to queue-up the jobs.
I still think we should be able to upgrade more than 1 building at a time if we have the resources to do it. But that, as they say, is a separate issue.
Cheers, and try to keep on having fun!
