Taxi Ways for St Augustine FLA

After landing ILS 31 at KSGJ St Augustine, I had the airport info chart up and the taxiways listed on the chart did not match the actual airport when taxing. ATC asked me to park at general aviation via Gulf across runway 13 on Echo then taxi foxtrot to gen aviation. None of these taxiways are listed on the chart all except RWY13? Am I doing something wrong? My charts are up to date 2412 rev1. MSFS2020 Desktop (Charts on tablet)

At a guess your ATC is using the scenery taxiways from the sim which in 2020 are incorrect.

Navigraph charts match those published by the FAA.

I figured the sim was incorrect. Do you know if the taxiways in 2024 are correct?

I would say no different and totally wrong.
