Script not executing after deployment to credit memo/RMA

Hello everyone,

I've been working on this script a long time, it is currently working on Quotations, Sales Orders and Invoices. However, after I deployed it to Return Authorizations and Credit Memos, it doesn't seem to work.

I checked the Execution log when editing a sales order and it executed, when I create a new Return Auth/Credit Memo, there is no execution log for those.

They are deployed and released. The code I am using is below, do I need to pull the returns and credit memos differently?
