Looks like I made a minor error in the update for the system under 4.13 and 4.14 (4.10, 4.11 and 4.12 are fine)… Inside of the C_Manager-LocalMap component, the second branch should be checking against IsOpen as shown below.
Apologies for the inconvenience. Please note that this will not stop Quest Map from working in any way, it will just mean that the local map continues to update even when it’s closed. The performance impact should be pretty negligible, but it’s an easy fix to apply 
I will submit updated files to Epic shortly to sort this out. Thanks for the understanding.
