Rotorcraft Commercial Pilot License "stop after holdshort line"

After finally being able to fly the full license, I have landed but it says to “stop after holdshort line” but doesn’t show where it is. Where is the holdshort line at Thun Airfield? I can’t skip to past it and there is not icon anywhere that tells me where to go.

I have found I generally don’t need to land but hover within a couple feet. I just move around that area. If you are saying it gave you zero indications when you landed, then pull up the charts in the EFB. If it doesn’t list it there, pull it up online. At least then you’ll know where the actual hold short lines are. I’ve only had this happen once and it was a remote (dirt) runway in Alaska and I never could find a chart. With a quick search, I found this for it, maybe it will help: https://skyvector.com/airport/PLU/Pierce-County-Thun-Field-Airport

Yesterday, I flew a skydive mission in career mode using the Cessna 172 several times, but I was never able to complete it. After every landing, I get a message saying “Stop after hold-short line,” yet no position marker appears in the usual blue color. And no matter where or how often I stop on the runway or taxiway, there is no progress! I taxied the Cessna 172 all over the airfield, but there is no confirmation to complete the flight or mission… ATC isn’t responding anymore, either.

I’ve tried three times; each time I’ve had to abort, and the flight doesn’t count as a success. I’ll never be able to advance in my career this way, because this is the only skydive mission worldwide that is currently unlocked and available to me.

And even though the engine is running, sometimes the propeller remains completely motionless and stands still!!

And why does it automatically have an outside temperature of -30 degrees Celsius? See instrument display on the left.

What kind of nonsense is this!?!
