Monks mound - placement rules change with patch?

[Shire]

I thought I was able to place next to any river previously. But today it is only allowing me to place next to navigable rivers. Converted a town to city specifically for the wonder, get the option in my other town, but the new one. Waited an turn and still no option. *sad panda face*

Probably a change they made in the patch. Previously they only said it had to be placed next to a river, no mention of a navigable river.

I closed down the entire app for the night, next day when I loaded it up, I could place it next to normal rivers. So looks like they have a memory corruption issue with the game. I know I saved and reloaded and the problem persisted. So it appears you have to close the game entirely to get around the bug.
