So I have a private survivak server for my friends and I, and ever since I updated it to 1.18, theres been lots of trouble. Yesterday, the server randomly closed down, with an "OutOfMemory" error in the logs, (I cant remember what it was specifically.) We waited about an hour before we played again, and once we tried starting the server, the status would be stuck on downloading, and the files would be gone. Then, you would have to wait a long period of time, and then all of a sudden, the files are back online. Same world, same structures, same everything. This has happened twice, and its getting annoying, plus I dont want to lose my world. Any ideas on how to fix this?

So I've been trying to break bedrock for a while, and it doesn't work even though I changed the paper.yml file to what I need to do. I linked my edited paper.yml file below. If anyone could help it'd be greatly appreciated. paper.yml
