Snapping posters to signs

Finally bought rising world after looking at it the last few months and wow what a good game, the digging and caving system alone is worth the cost. I noticed u can't snap posters to signs, or I couldn't get it to work, would be nice to do this for signs, I also read there might be a water update in the future, i would like to see some of the caverns u run into filled with water en your digging if u break through it can fill up your shaft or u have to find a different route
anyways just a few thoughts but a very
good game none the less
