Friendly reminder, check your stamp when entering Thailand. I completed my first visa run and they only gave me 60 days. I went to immigration the next morning and was told it would take 2-3 days to fix. They sent me to immigration at the airport for faster service. So, I did that and it was resolved in 20 minutes. So save the trouble, and look at the stamp before walking away from the immigration officer when entering Thailand.

Full disclosure, I didn't present my printed visa to the officer because I know he can see the visa on the computer when he scans my passport. He just didn't notice it on the computer. Lesson learned for me.
