this is an error on developer's part, this is not mod related, i played without the mod to replicate this error, it still exists
so the bug is that, after laura's second date [mandatory] - when mc goes home, Amy's scene is triggered instead of laura, however this doesn't cause the game to break, but is unusual, you can fuck amy and then leave to enter laura's room and fuck her too, then sleep and next afternoon meet clarissa at her place ..
this bug was not there in laura part 1 [0.84], but is there in part 2 [0.84.5] if you play laura's quest from beginning [0.84.5 i.e play both part 1 & 2 together in 0.84.5] you will trigger this bug, the error is on the developers end, not the mod
