[Bug Report] Auto-Open Map Coords sometimes doesn't work

[Forien]

Describe the bug
The Auto-Open Map Coords usually works very well. However, sometimes during Hunt Trains, some flags are not opened. At first I thought it happens when I'm holding right click or doing some actions, but several times flags were also not opened when I was idle.

To Reproduce
Steps to reproduce the behavior:

1. Enable Auto-Open Map Coords
2. Go to Hunt Train
3. Sometimes (randomly?) map doesn't open and flag is not "clicked"

Again, hard to reproduce as this happens randomly and majority of the time feature works correctly. I would love to provide more context but I am having hard time to narrow down what causes it

Expected behavior
Map opened every time a flag is posted to chat on /shout or /yell (which I have enabled in whitelist)
