What should I do if I lost my TM.6 card before leaving Thailand?

The individual is concerned about losing their TM.6 card before departing Thailand and is seeking advice on whether this would pose a problem at immigration. Community responses reassure that it is typically not a major issue; they suggest informing the immigration officer about the loss, obtaining a replacement form at the airport, or reporting it to the nearest immigration office if needed. Some emphasize having a photo or copy of the card for future reference.
