Your departure date in your passport most likely is good enough to verify when you left.
My experience with Thai immigration was being made aware I had overstayed my visa by two months. It was a misunderstanding on my part. In any case, the Immigration police recognized it had indeed been a mistake. They warned me I needed to leave Thailand immediately and leave Chiang Mai directly out of the country. I was charged ฿20,000 and it was marked in my passport. Since then, returning to Thailand, obviously my violation would be noted. When immigration notices the violation on my passport, the only response I’ve ever seen is a smile.
If you have fulfilled your obligations for reentry, I wouldn’t be expecting any additional issues. Showing up well groomed, wearing clean clothes, and showing respectful deference goes a long ways in Thailand.
