I have experienced this issue with both results, ever since I enabled "Always Transportalate" on my spellcaster sims. Sometimes the sim transports to the magical grounds, then transports back and walks to another area and performs the duel; other times the duel is cancelled completely after they transport to dueling grounds. It appears to be dependent on what the challenged sim is doing after accepting the challenge.

Here is a link to my save file with the issue. https://drive.google.com/open?id=1thAGX7Pc_M9ZqgrOphUUvh7DNWbUzQIQ Either sim can be used to challenge a magical sim.
No cc/mods, never used. Base game/RG/IL/ROM + freebies.
