Hello! If a provisional patent is not converted into a non-provisional patent after a year, can this still be done at a later date with some legal disadvantage in the meantime; or is the whole process reset to zero and a new application would need to be filed?

Essentially yes, the PPA will have lapsed and you will need to file a new patent application which will get a new priority date.
