Thanks for letting us know you got a 30 day Extension of Stay based on being unable to travel. What kind of permit to stay you had to be inside Thailand and how many times did you already applied for Extensions of Stay?
Don't worry, all those extensions and the rest of you history of being and living in Thailand are all in the database. You tell nothing new and hiding by uploading a blanco page does not work
By Thai law, every person who arrives at a new address within 24 hours needs to be registered at the local Immigration Office. If you left Phuket and stayed elsewhere you need to report that you are back in Phuket, BUT some Immigration offices are more lenient with enforcement after holidays in country or even short visits abroad.
Call or contact the local Immigration Office about their enforcement of the rules.
