If you left the country and came back, or stayed at another place who registered a different TM30 than where you normally live, you will need your landlord to file another TM30.
I was stopped at the front booths, and brought back for a talk. The officers looked at my travel history and they literally said "We can not let you in because of xyz. Come back when you have a proper visa". So I was denied entry.
After being told this I was close to having a panic attack and was shaking and very distressed since all my stuff was still in Thailand, and the sweet but stern immigration officer lady took pity in me.
And then we had a productive conversation about why I had been there so long and why I had not gotten a proper visa, and when I was heading home.
The compromise was they would let me in if I could show proof of monthly income to support my stay, and order my ticket back to my country ( flight within the next 60 days ) right then and there, and whenever I decided to come back to Thailand it was with a proper visa, not a visa exemption.
