I'm using a big modpack, and it takes a long time to login to a server (I don't know which mod is causing the slowness). By the time the game starts, I get the line Waypoint manager is not ready after 25 attempts. Giving up and discarding 1 deferred events in the client log, and waystone syncing doesn't work.
Could you make the waypoint manager's timeout configurable, or remove the timeout altogether, so it can be used on servers with slow logins?
