Hi @Flak this seems to be a pretty wide spread issue. There are about 7 different forum posts in the last month each with multiple votes and comments that have been closed due to not being able to reproduce.
I have a map with this issue and have noticed when it’s getting a new and updated or has higher player counts the issue is way better. Maybe higher quality servers are reserved for maps with more players but the lower player count servers can’t handle maps with high actors and heavy verse. It also seems to just be an issue with the server initially loading the map because it works sometimes and once it does let you in it’s always been fine.
