I believe the problem with the "add population" feature is that the latest game patch disabled the ability to click on the buildings, so now the icons cannot be "greyed out", which does not allow for the population to be bumped when using the trainer. I downloaded the trainer again today to make sure I had the latest version. Everything worked per the instructions except for the population cheat. This is my observation, though maybe I missed something. Perhaps you could look into this. By the way, thank you for the wonderful work you all do at cheathappens.
only the "add population" feature does not work...all the others are ok..this only happened after i loaded the new "steam addons..namely.."create artifact".and "Powerfull Lords"..i think these new addons are the problem??there are 4 addons..??
