@Babbuc49 thx i can do it under my board.

so may i ask where i can report a bug? it is an important move so i stop continueing the game

In two different games, when I pick advanced science tiles, I cannot find the basic tiles i wish to cover ( both were 1mine 1QIC). It shows other basic tiles but missed 1o1q one. It happened twice,so i doubt if this is rules or bug?
