A simple check before the memcpy avoids the crash.\r\n\r\nFurther info: The world was converted from 1.12.2 to 1.13 (now 1.13.1) with setting the repop flag on some water chunks (which simply causes them to be regenerated in 1.13). The affected chunks might be some of those and/or have not been explored again in 1.13. Other such chunks load just fine, though.\r\n\r\nEdit: Some more investigation revealed that the affected chunks report an \"Unknown\" biome with \"Unknown\" or valid blocks. Chunks with \"Unknown\" blocks, but valid biome do not seem to cause a crash."},"comment":{"url":"https://api.github.com/repos/mrkite/minutor/issues/comments/428321686","html_url":"https://github.com/mrkite/minutor/issues/143#issuecomment-428321686","issue_url":"https://api.github.com/repos/mrkite/minutor/issues/143","id":428321686,"node_id":"MDEyOklzc3VlQ29tbWVudDQyODMyMTY4Ng==","user":{"login":"jamesmule","id":30132577,"node_id":"MDQ6VXNlcjMwMTMyNTc3","avatar_url":"https://avatars1.githubusercontent.com/u/30132577?v=4","gravatar_id":"","url":"https://api.github.com/users/jamesmule","html_url":"https://github.com/jamesmule","followers_url":"https://api.github.com/users/jamesmule/followers","following_url":"https://api.github.com/users/jamesmule/following{/other_user}","gists_url":"https://api.github.com/users/jamesmule/gists{/gist_id}","starred_url":"https://api.github.com/users/jamesmule/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jamesmule/subscriptions","organizations_url":"https://api.github.com/users/jamesmule/orgs","repos_url":"https://api.github.com/users/jamesmule/repos","events_url":"https://api.github.com/users/jamesmule/events{/privacy}","received_events_url":"https://api.github.com/users/jamesmule/received_events","type":"User","site_admin":false},"created_at":"2018-10-09T19:33:08Z","updated_at":"2018-10-09T19:33:08Z","author_association":"NONE","body":"@EtlamGit yeah, sorry about that, I was expecting it to be just a bug in Minecraft's conversion code"}}
