New Server - Bug Problems - can you help me?

Hello Guys,

I got a “Little” Problem with my new Rust Server. I bought one from g-portal today and there are some users that spawn in the Air and then fall to their Death. Did i do something wrong or can i somehow solve this problem? The only thing i found on google was a 6 month old post on steam without problem solving.
