I compiled Kstars and indi from scratch on Ubuntu 20.04, using indi 1.9.1.
I started an only simulators profile:

Then when in Align module I get the following behaviour:

Goal: Find the position/centre coordinates of a picture taken before.
  1. I switch to mode „Sync“
  2. Then Load&Slew my picture
  3. the Solver runs, finds coordinates, updates mount position and then
  4. The alignment module switches to „Slew to target“ mode
  5. aquires an image
  6. due to wrong exposure settings fails
expected behaviour is: 
4. stop

Rationale: If „sync“ is selected, the telescope should already be „pointing“ at that patch in sky.
