Soo… shutting down the server for maintenance obviously affects gameplay. It’s also necessary for developers to fix glitches, etc…
JWA is very sensitive to timing in that, important events that can take just a few moments can make big differences to a player ( darting epics, launching scents …)
If we, as you player base/clients, may be at risk of the game shutting down for updates (which we hope continue to happen to make the game better) …
I would suggest: an in-game player wide alert that says something like:
an update will occur in X minutes
This will give us time to finish battles before starting new ones and also warn players to not launch scents at that time.
Just my thoughts on what seems like a big problem, with a simple solution.
