After Quartet summon, I cannot use zenna and protect code talker to summon firewall that i bounced back with his own effect, it lets me try, but then it won’t let me actually click on the highlighted cards to allow me to summon (the zenna and protectcode were not summoned with quartet so they don’t have a restriction, the game allows me to try and summon using them and it highlights them but it wont let me actually click on them. I can continue the combo and even use them after I use orcust cards, however.
If the game highlights a card as if you can activate it or use it as material, but you cannot click the button, then thats the Unity resolution bug, which prevents clicking on certain UI elements even though the game is recognizing them as something you should be able to interact with.
Unfortunately theres nothing we can do to fix it, as its an issue with the Unity engine itself, which is closed source, which is part of why Omega 3 wont be using Unity
