So, this has been happening to me for a few days, and I've confirmed from my friends that it's not just on my platform and not just to me that it's happening. It happens on Phone, PC and iPad/Tablet, as far as I have seen.

When you try to change your Personal Settings, everything that you tick becomes unticked (you can't see it, but it takes action) and everything that you DON'T tick becomes ticked! Try it yourself if you don't believe me.

The only way that I have found on how to fix this, is to completely exit GrowTopia and start it again. Please fix, it took me a long time to realize because I couldn't hear everyone or read bulletins boards and signs. It is going to confuse A LOT of people.
