Adventure Mode: "On the Hunt" quests do not work after save/load

**Describe the bug**
After getting a "On the Hunt" quest, then saving, then re-loading the game, the creature never spawns, so it becomes impossible to finish the quest.

**To Reproduce**
Steps to reproduce the behavior:
1. Get a "On the Hunt" quest. Track it so you can see the arrow leading to the creature.
2. Save the game.
3. Re-load the game.
4. The tracking arrow no longer appears, and even after wandering for a long time, it's impossible to find the creature.

**Expected behavior**
After reloading, the tracked creature should re-appear, as well as the tracking arrow.
