Another new problem just since patch 1.71. The terrain tool was one of the biggest casualties of the changes. Now if I use the eraser tool and switch to the paint tool...the sizing options are greyed out. Sizing is a problem anyway because as I've already reported it blurs when it's on max size setting. I can use the lower settings but if I've used the eraser, I have to go back to the eraser to increase the size, then go back to paint. It wouldn't let me increase the size on the paint setting. Sometimes it swipes to paint now but sometimes it doesn't. It wasn't swiping at all but now it's random.
I'm building in shorter stints. Just a couple of hours then stopping and taking long breaks from it as it's something I love to do but it's just resulting in pain in my hands and aggravating a chronic pain condition and building from the top down is just nausea inducing, I keep instinctively switching to that because of the menu. Especially if you are editing small rooms like hallways as build mode is so dark now, lights go off when you return to a build or edit a current lot. I have to switch all the lights on to enter build mode but can't do that on Freebuild.
Nearly 2 months now and the code is still in the game for the old controls mode because they keep popping back in my game. It should be possible to revert back to the original format. My fear is that there's no plan to do that and just to look at the bugs rather than the discomfort and inconvenience. There's just no way of knowing.
Edit: attached is an image of the terrain tool sizing, greyed out. I had to go to the eraser tool and resize it instead then go back to the paint tool. I then had a similar nightmare trying to resize the lower terrain tool which was stuck in the middle size.
