got some problems with my Tower Defense project (Episode 19 and following), my upgrade and sell buttons doesnt work ingame, the onClick event never gets called.
If i put a new button on the overlaycanvas and add the onclick event, i can upgrade my turrets, so i would say something is between the other buttons and my mouse.
Like Brackey, who had problems with the “graphic raycaster” from the topcanvas.
I someone want to take a look: https://drive.google.com/open?id=1x2AvTxFrto2wM7_QYdO6b6G7nhdRloJF
Thanks for any help!
