CM:H may return incorrect hero Id(s) when Scholar is triggered before hero meeting screen, when there is another hero nearby

Okay this may sound confusing. Let's reproduce the bug step by step.

1. Get 3 heroes next to each other

2. Give Scholar to one of the heroes, also give this hero all the spells
3. Save the game
4. Use this hero who have Scholar to visit another hero to trigger Hero Meeting Screen
5. Close the Scholar dialogue and enter Hero Meeting Screen
6. Use the testing script to check out whether any of the hero Ids returned from CM:H are wrong.
7. If nothing goes wrong, reload the save game saved in #3 and try again from #4.

Save game for testing (test from step #4 with it)
and video

Note:
- It doesn't matter which hero has Scholar (no matter left or right)
- The hero with scholar can be in any position among the 3 heroes
