I'm not sure why removing a citizen would add two food instead of removing it - that's rather odd!
1.9x is the same as 190%. In English the "x" means it is a multiplier, and it appears that got translated incorrectly to a percent sign. I find it slightly easier to read 1.9 than 190%, but I've started to think this is not a universally shared understanding, so I changed it to a percentage for the next version.
