It is very difficult to increment the max number of citizens under settings/gameplay by 1 using the slider. I do not know why – it seems to want to jump 2 citizens.
For example, I started out at 20 by default and had no trouble sliding it up to about 23 or so. I was not particular the first time. I just wanted a few more people, didn’t want overkill though. So I nudged it randomly.
Then I only wanted 1 person. I just couldn’t get it to go from 23 to 24 for the life of me. So I settled on 25. I tried lowering it then raising it, I tried all different ways to to increment it – it was just too hard to increment it by 1.
Again when I went from 25 to … 26? This time I was able to get it to 26, instead of 27, though it was difficult. I had to lower it and then raise it. It was very jumpy, kept hopping to 28 instead of 27.
I do not know why it is so sensitive. I did not go into my mouse settings to try to see if changing that would help; partly because I didn’t think of it at the time and now that I think of it, well I never would. Shouldn’t have to and too lazy and I’d probably just settle for one more or less than what I was aiming for … but what I think would be an ideal solution would be to use a -/+ on the far left and right of the bar to increment and decrement by 1 in addition to having the slider. That way people who do want to move it up or down a large amount at once can do so, but then any fine tuning can be done. I really don’t know why I’m having so much trouble with that part of the interface.
