(a) Except as provided by Subsection (b), the reenactment, revision, amendment, or repeal of a statute does not affect:
(1) the prior operation of the statute or any prior action taken under it;
(2) any validation, cure, right, privilege, obligation, or liability previously acquired, accrued, accorded, or incurred under it;
(3) any violation of the statute or any penalty, forfeiture, or punishment incurred under the statute before its amendment or repeal; or
(4) any investigation, proceeding, or remedy concerning any privilege, obligation, liability, penalty, forfeiture, or punishment; and the investigation, proceeding, or remedy may be instituted, continued, or enforced, and the penalty, forfeiture, or punishment imposed, as if the statute had not been repealed or amended.
(b) If the penalty, forfeiture, or punishment for any offense is reduced by a reenactment, revision, or amendment of a statute, the penalty, forfeiture, or punishment, if not already imposed, shall be imposed according to the statute as amended.
(c) The repeal of a statute by a code does not affect an amendment, revision, or reenactment of the statute by the same legislature that enacted the code. The amendment, revision, or reenactment is preserved and given effect as part of the code provision that revised the statute so amended, revised, or reenacted.
(d) If any provision of a code conflicts with a statute enacted by the same legislature that enacted the code, the statute controls.
