Visa Non-O & TM30

[MarkBR]

I am on a Non-O visa, and have been doing my 90 day reports no problem visiting Chiang Ma immigration and going to teh little window, they looked at and typed into the computer printe dme out aofficial form, and that was it - nothing mentioned about the TM30.  However, I used the online system for my last 90-day report & it was rejected, and it said my TM30 was wrong , but this TM30 location was from before I did the previous 90-day reports when nothing was mentioned?   I have the printed officially stamped paper from my previous personal visit to approve my 90 day report.

I am now forced to go to immigration to try to find out what is going on?

My question is the TM30 still required if you are on a Non-O visa, and nothing was mentioned the previous 3 times you went to get your 90 day report done?

I am very confused currently as to what is required?
