Made three attempts to build new island strategy. Each time at some point I must have bumped the "ALL" button because all objects returned to tray. Much time lost! Not sure I pressed all button the the third time. Might be a bug. If not there should be a confirmation dialogue before ALL applies..
I agree completely, a confirmation message is much needed, because the same thing happened to me earlier. It made me so mad that I finally signed up for the forum so I could comment on your post haha. I will admit, the first time was my fault for sure, I had to set my phone down for a moment and the screen timed out. Lost everything. Determined, I started over, was almost done once again and then apparently must have somehow accidentally hit the "All" button. The third time I started over, I am pretty certain I didn't hit All but much to my dismay everything returned to the tray. It was at that point that I gave up on the editor and went back to doing it "the old-fashioned way" because at least that saves as I go lol
Aside from decorations, I was almost done a few times lol so as long as you stay away from the All button and save quickly I think you should have a fighting shot.
I've said this many times with many buttons from many games. Woe is the gamer that prematurely presses the button
You loose nothing for trying I did finally redesign using the editor and it worked. You just cancel and all is as it was. Four tries and I finally got it to work. I moved very slowly and was mindful of the ALL button continuously!
