First off, regarding your 'I'm not that stupid" comment, nothing anyone suggests here is meant to be construed as an insult to your intellegent. Not everyone is on the same knowledge level with game play or technical issues, so it's always best to never assume anyone knows what you do. When people are having troubles and get frustrated, sometimes simple things get overlooked. You'd be surprised at the number of help threads where everyone started out with suggesting the high-tech fixes, none of which worked, only to have someone come in and say, "Hey, by any chance you didn't happen to accidentally turn off/on (insert seemingly no-brainer thing here), did you?" only to have the perfectly intelligent individual with the problem do a facepalm because that, indeed, was the problem.
Cheats. No, they aren't case sensitive, just easier to read and make sure you've typed it with no spelling errors if the caps are there. Look:
boolprop testingcheatsenabled true/false
boolProp TestingCheatsEnabled true/false
It's even more evident with longer cheats codes, like this one:
boolprop allow45degreeangleofrotation true/false
boolProp allow45DegreeAngleOfRotation true/false
Both the caps and no caps versions are the same cheat, and both do the same job, but the second one is easier to read isn't it? If you type it in wrong and the console comes up with a lot of text then, as Tenshii said, you've made a error somewhere. You either put a space where there shouldn't be, or spelled something wrong.
My guess is you have a download causing it, probably a conflicting or outdated mod. Is this happening in all your lots, or just the one? Try taking the downloads folder out and running your game without it. If it runs just fine, then it's something in your Downloads folder.
