Hey devs, I discovered in my singleplayer game after I put down a stone water reservoir on the ground, log out, log back in, the status will switch from irrigated to not irrigated and then stays at not irrigated. This happened every time I put down a new reservoir. It happened first in K5, but also in J5. I assume this is a general bug for all grids? Would be cool if you fixed this, the desert is not the rainiest place of all times.
