I think it's the impact of the infinite loops on her psyche.
For an untold number of years, everyone around her would snap back to a default state every 4-16 months, so in her mind, they've become little more than NPCs. Prior to this cycle, literally anything they'd have to say is something she's likely heard dozens, if not hundreds of times.
And now the rules have changed, and even though she knows the rules have changed, she is so deep in that infinite-loop psychosis that she can't bring herself to treat the other characters as actual people and LISTEN to what they have to say to her. It's why she didn't tell Ayane the VERY IMPORTANT information about Ami, Ayane's still an NPC in her mind.
