locking your base, simple, but would help
This morning when I logged on, I noticed I had a piece of wall missing. It had accidentally been moved the night before without me realizing it. I was looking for the better part of a half hour before finding it stuck in an inconspicuous corner.
Now once i had found it, fixing it wasn't the problem; it was the fact that all night long i had a hole in my walls where enemies could get in easier. Luckily all that happened was my town hall was sniped. Over the course of looking for the wall though i thought to myself, "Hey, you know what would have helped avoid this situation? If we had some way to lock our base design to prevent accidentally moving things."
I accidentally move stuff all the time, and I'm sure I'm not the only one. Most of the time i catch it, but still, having the option to lock our base design would help ease some frustration just a little.
