What are the recent changes in Thailand's immigration process for marriage extension of stay under consideration?

I have the stamp for underconsideration being for 1 year extension of stay based on marriage. Been doing this for 10 years now. Today recieved a phone call from immigration wanting an update on bankbook. The required funds have always been in the bank and on appplication for extension letters from the bank were produced as required along with all the other documents required. This year was the first time the immigration police did not come to our home as they normally do after application. So it seems like they are now checking on funds whilst under consideration. I went to the bank to update the bankbook at the ATM and supplied copies to immigration of which they wanted the same day Immigration in my province. did say that Immigration in BKK is making it harder. All documents are sent to BKK for approval. So lets see what happens now.
