I started playing yesterday with the controller in Type A configuration. In that mode, you hold the left trigger to aim Blink and you release to cast. No problems all night.
Today I start it up and now the hold to aim doesn't work. It just instantly casts the spell and you blink it whatever direction you happen to be facing.
I've tried restarting the game, restarting the PC, re-connecting the controller, nothing makes it behave the way it used to.
Aim still works for the Possession ability. So I think that rules out the controller being faulty.
I tried switching the configuration to Type D, which remaps the ability trigger to the right bumper and it works fine.
Has anyone else had this issue?
