Several pools of water in the game have descriptions that indicate that they collect water (and thus refill) over time. I've made an update to the script that was handling these, so if you come across a pond, spring, pool, oasis, stream, or anything like that that seems like it should refill over time but does not, please typo it in the game so that I can go through and fix them later. The description should make it clear whether or not it should refill - i.e. it should say something like, "Water trickles slowly down the cave walls and accumulates in a deep pool in a depression in the stone."
As a side note, please do not wish up about these, just typo them.
You rock.
Thanks Nusku. For your effort.
