Replaying on xbox series x - w/ festering skies and ancients DLC... Phoenix Point gane balance is better but it is still a "beautiful mess" of bugs.
Stuck on a Haven defense mission with Scylla - restarted the mission Five (5) times halfway through a capture, because the combat ux breaks after entering grenade aim mode and stops responding to any controller buttons. Cant fire, cant switch soldiers, cant even quit the game - have to kill the game from the console hub.
From switching weapons and inventory items, the common pattern I've seen is it tends to happen on soldiers with the vita grenade equipped (or right after switching from them to another soldier).
