For a little over a week I have not been able to publish maps with more than 50k locations. All of the maps in question have published earlier without issues. What I get is a 504 error code after 60s with this in the response "504 Gateway Time-out".
It happens both in the map maker and by pure API calls. In the map maker it results in the error message "Unable to publish map".
The specific request URL in question: api/v4/user-maps/drafts/{mapId}/publish
It is a very consistent issue. Publishing 45k locations works, but also takes 56-58 seconds, barely making it within the timeout.
This issue stops me from adding Paraguay to all my maps, including An Informed World, A Pro World and A Rainbolt World which are all currently used in competitive duels.
