After a jokingly excessive command by friend, server times us out and shuts itself down

Hello,

After my friend jokingly set randomtickspeed to 999999, the server froze, crashed, and since we've even changed tick speed back from console, the server will time both of us out and refuses to load any chunks.

Log: https://mclo.gs/hE5H2aj

Aternos UN: ohohdeerling

Server name: alterzone

If anyone knows how to read through logs and tell what errors it's spouting out, please let us know! Thank you!

Have you restarted the server after changing the tickspeed back to 3?

cammiechan is the other person involved with managing the server, so yes we have, and it still has the issue
