For the Linda night scene bug just open the console (first you need to enable it with unren.bat).
Then type (or paste) the following code (copy and paste all of it):
nsb_box.ml_nsb_s[0].number = int(nsb_box.ml_nsb_s[0].number);
nsb_box.ml_nsb_s[1].number = int(nsb_box.ml_nsb_s[1].number);
nsb_box.ml_nsb_s[2].number = int(nsb_box.ml_nsb_s[2].number);
nsb_box.ml_nsb_s[3].number = int(nsb_box.ml_nsb_s[3].number);
nsb_box.ml_nsb_s[4].number = int(nsb_box.ml_nsb_s[4].number)
Then type (or paste) the following code (copy and paste all of it):
nsb_box.ml_nsb_s[0].number = int(nsb_box.ml_nsb_s[0].number);
nsb_box.ml_nsb_s[1].number = int(nsb_box.ml_nsb_s[1].number);
nsb_box.ml_nsb_s[2].number = int(nsb_box.ml_nsb_s[2].number);
nsb_box.ml_nsb_s[3].number = int(nsb_box.ml_nsb_s[3].number);
nsb_box.ml_nsb_s[4].number = int(nsb_box.ml_nsb_s[4].number)
