Refreshing doesn't work, and the end-result of the bug led into ANOTHER bug, where it wouldn't let me undo my tile selection. This second bug has already been reported by someone else.

I don’t know what turn. It was late in the game. The problem is that the game log has no record of an error because it just records that I made a selection. But as mentioned, I only made that selection because it wouldn’t let me make the selection I wanted and wouldn’t let me undo my choice.

Twice in the game, I attempted to use two wilds to make a selection. the game acted like it would let me by opening up all of the tiles for selection. It allowed to select any of options. Once I confirmed my selection, I would get an error message that said to choose a tile to select stones. On each of these turns, I had to end up just deselecting on and picking a single stone and not using the take any piece option.

I did try refreshing and this did not help.

I came here to report this bug, where selecting two tiles of the same shape to use as "wild" didn't seem to work. I finally realized how it works by re-reading the instruction booklet PDF. I think the prompt in BGA when you try to take this action should be more descriptive. Here's what I tried to do:
1. select 2 of the same shape from my hand
2. select the river tile that I wanted to take the glass pieces from
3. click the button to confirm
4. there's a message prompt that reports an error (I can't remember the exact text but it wasn't descriptive enough for me to figure out what I did wrong)

Here's what worked (and does seem to match the instruction book, however, it isn't obvious from the game on BGA). I can't recall if the tutorial was specific about this, but it's definitely not intuitive:
1. select 2 pieces from your hand that are the same shape
2. FIRST select the river tile you want to place your tiles onto (I think this highlights the tile black)
3. NEXT select the river tile on either side of the previous one to take the glass you want (I think the highlight for this one is red)
4. confirm your turn with the confirm button
It's confusing because you need to select where you want to put them first and then the tile with the glass you want to take. I assumed I selected the tile you want the glass pieces from and then confirm and then there would be another step to choose where to place the tiles you're giving up from your hand. It totally makes sense that it's the opposite in the actual game, but just wanted to note that it's not clear in the interface and that they "error" message that pops up isn't clear. It could be more descriptive like, "first select the tile you wish to place the glass from your hand (it will highlight black), then select the tile you wish to take the glass from (it will highlight red)."
