I tried with both a Carpenter and a Mine from numbered depots. I also tried buying a Mine from the central depot, and that did not work either.

This just happened to me on table 212040011. I placed a town hall and bought a tile from the board that I wanted to place, but only the tiles that were already in my inventory are showing as legal.

I had a similar issue in table #238824968 right about move # 227

I placed a castle, was given the option to buy from central/black depot, but then denied the ability to place that tile with the castle bonus. I have done this many times in the past, but this is the first time I have had knowledge tile #6 in play--even though I was buying with silver instead of workers.

I also have had this same issue, also with knowledge tile #6 in play

F5 did not solve the problem.
tried 4 or 5 times. with an wothout F5 inbetween: fully repeatable
No screen shot. Sorry. Surely you can replay the game?!

The boat tile does get a green circle in replay. It's didn't get a green circle during actual play.

Came here to report just this problem: table 422347373, move 183.

I've placed my castle and the action bar says this: "Castle advantage: you must take a tile, place a tile, sell goods, or take workers (you may buy a tile beforehand)"

Okay, so I've bought a tile from the centre depot (using silverlings, not workers), but now I cannot place this newly purchased tile with the castle's ability. This new tile does not have a green outline around it the way the other previously acquired tiles do; when I click on this new tile, it has a blue outline, and no outlines show up on my player board for this type of tile.

The animated image posted by Jan de Graaf immediately above this comment shows precisely what I'm experiencing.

However, in my case, F5 /did/ solve the issue, so I've been able to proceed with my turn. Nonetheless, this is, at the very least, a display bug, so I'm upvoting it.

I'm having the same issue in my game right now. well i am not using the tile 6 function cause i bought from the central depot but i do have that tile played, so i guess it is also because that. what do i do with this game now?

okay, reloading in the middle of the move worked, still super annoying. would be great if that gets fixed. i mean the first mention on this report is 2 years old

I had purchased a boat tile, and was unable to place it using the castle bonus.

Same issue. Happens to me every time I try in every 2019 Edition game.

This applies to both the Castle and the Town Hall.

After playing Castle or Town Hall, the hint correctly says "you may buy a tile beforehand." And, indeed, the interface does allow a tile to be purchased. But then the Castle or Town Hall bonus action does not allow the new tile to be placed--only tiles that were already owned.

Thanks to those who mentioned that reloading the game after purchasing the tile fixes the problem. I had not previously been aware of that, and it just saved me in a big tournament play.

Same issue. Happened in table538949236.
Can't a place a tile with a castle after i bought it with the knowledge tile 6.
Either with silverlings or workers both doesn't work.
Blue circle around it doesn't appear while on other tiles it does.

Can't use tile 6 to purchase tiles.
