We've had no complaints about server issues and I haven't seen reports of server outages in a while. The only downtime that the servers have had recently are for scheduled maintenance which was announced in our Discord server beforehand. Slow load times and not being able to go through map links is a connection issue. Since nobody else is reporting this but you, it can only be a connection error on your end. We have thousands of active players, I think more than one person would've said something if it were a problem.
The thought that it's something that only happened since the update doesn't make sense though, since the client update doesn't effect the database or servers.
Besides, PRO was never build with such a large playerbase in mind. It was build for 500 players on one server, max. With numbers like these, I wouldn't expect PRO not to have some turbulence, especially during an event.
Since this isn't a bug, or something we can really fix, I'll lock the post. Thanks anyway for reporting your concerns.
