Rolls totalling 1 auto-fail, and rolls totalling 20+ auto-succeed, when it should only be "natural 1s and 20s"

[anthonyronda]

What happened?

1. Roll a to-hit 1d20 with a natural result of 2 against an AAC of 1
2. Modify the result by -1 (1 vs AAC 1)
3. The roll fails

Also

1. Roll a to-hit 1d20 with a natural result of 19 against an AAC of 21
2. Modify the result by +1 (20 vs AAC 21)
3. The roll succeeds

What is the expected behaviour?

Attack rolls with a modified result of 1 are allowed to succeed if it hits the target armor class, and rolls with a modified result of 20 are allowed to fail if it misses the target armor class
