it works well enough, but you need to close and reopen chrome to reset it, which is super inconvenient TBH.

my theory is that it has something to do with the daily reset, in addition to the arena changes made back in July 2018.

my suspicion/suggestion/concept is perhaps that the timer/loop is stuck if it's open during the daily reset, if you have the browser open when it resets during the day/night.

It affects Pachinko, Arena, Contests and Missions from working or auto-firing, even though the loop finishes.

Changing the setting won't "hold" in memory if you reload the page, or tab in this state either, it repopulates old settings. the settings can be toggled, but on reloading, they go back to their 'entrenched' position.

I would suggest having a debug in the console that prints out the timers as a check, after each loop has finished, or validates/resets any extremely long timers against the Home page's timers, to know if the autoloop is having issues after 25+ hours in memory.

Having watched HHA get stuck for 45 minutes trying to complete a 5 minute mission...

you can't reload the page.
you can't reopen a new tab, and close the old tab.

you have to restart the whole browser to clear the memory/settings and relaunch the script.
