[BUG] Inconsistent Notable Level
This bug creates a situation where quest locations do not properly recognize the player's current notables level. This can create a situation where some quest locations are accessible while others that should, are not. An example is provided in the following two screenshots:

Proper Notable Level/Accessible: In the above image, the ancient ruins are shown reporting the correct adventurer/notable level of 3.

Improper Notable Level/Inaccessible: Checking the treasure chest just below the accessible ancient ruins reveals that the player's notable level is purportedly two, instead of the correct value of three. This is not merely a display error--attempting to access it results in failure.
Also of note is that, at least in this example, when I attempted to access the ancient ruins I was able to do so. Immediately after doing so, however, the game crashed. Reloading the game from the auto-save made on the turn before resulted in a new array of quest locations, map wide. All of those resulting and different quest locations also reported the wrong notable level (i.e., 2 instead of 3), and were inaccessible when they should have been.
