Lazy Cop is getting their reports too early. If they investigate someone on Night 1, they should get the report DAY 2, not Night 2. Right now, they're getting it on Night 2.

If they investigate on Night 2, they should get their report on DAY 3, not Night 3. etc.

The role description is correct; the Lazy Cop should "receive their report of the person's alignment on the day after".
