Their iOs Minecraft v0.15.0 app crashes. The Pocketmine-MP Server recognises them joining, but after the app crashes, the server states that they have left the game, \"logged out due to timeout\"\r\n\r\nTo help me work out where the problem may lie, I have created a new Pocketmine-MP Server with the exact same PHP Binarys and .phar file. The set up creates a new blank world, which works fine with the  iOs v0.15.0 app. I then swap their previously World directory and files that worked with v0.14.3 with the created one and it no longer works as per above. \r\n\r\nI can only assume that the new .phar file or the v0.15.0 app is incompatible with some data in World files. I do not know how to determine what is wrong. My children have done a fair bit of work in their world and I would hate for them to lose it all like what happened way back in 2014 when Minecraft PE went from v0.8.1 to v.0.9.0. There are no crash dumps. I have attached our Worlds directory for testing if possible.\r\n\r\nThanks in advance for looking at this issue.\r\n\r\n[worlds.zip](https://github.com/PocketMine/PocketMine-MP/files/329042/worlds.zip)\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/PocketMine/PocketMine-MP/issues/comments/232222191","html_url":"https://github.com/PocketMine/PocketMine-MP/issues/4216#issuecomment-232222191","issue_url":"https://api.github.com/repos/PocketMine/PocketMine-MP/issues/4216","id":232222191,"user":{"login":"ZedCee","id":20411465,"avatar_url":"https://avatars.githubusercontent.com/u/20411465?v=3","gravatar_id":"","url":"https://api.github.com/users/ZedCee","html_url":"https://github.com/ZedCee","followers_url":"https://api.github.com/users/ZedCee/followers","following_url":"https://api.github.com/users/ZedCee/following{/other_user}","gists_url":"https://api.github.com/users/ZedCee/gists{/gist_id}","starred_url":"https://api.github.com/users/ZedCee/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ZedCee/subscriptions","organizations_url":"https://api.github.com/users/ZedCee/orgs","repos_url":"https://api.github.com/users/ZedCee/repos","events_url":"https://api.github.com/users/ZedCee/events{/privacy}","received_events_url":"https://api.github.com/users/ZedCee/received_events","type":"User","site_admin":false},"created_at":"2016-07-13T00:33:02Z","updated_at":"2016-07-13T00:33:02Z","body":"I've generated some fresh maps, sans Pistons, default flowers, removed chests...\r\nAlbeit I experience with no issues from generated abandoned mine shafts or any of the dungeons, but towns just will not work correctly.\r\n\r\nI have attempted several fixes, almost nothing works short of trimming the chunks which is no good for a custom map:\r\n1. I've deleted all entities, villagers, chests and anything that builds.\r\nAfter about 30 or so blocks became corrupted with repeat logins, deleting the path block and crop blocks, the crashes subsided.  The map now with massive holes is fully accessible (the problem was in the 2/4 clockwise) and editable in MCEdit.\r\n2. PMImporter_dev managed to convert the file to mcregion with no issues, but even with the changes Beetroot and GrassPath are replaced by update! blocks.  The map is fully accessible and nearly undamaged, but has an unknown number of update! blocks and is uneditable in MCEdit due to SkyBlocks (a light block placed in the old world format).\r\nBlocks noticeably 'update!'ed were GrassPath and Beetroot, but all entities were left intact, and suffering no problems from chest or spawners  too.\r\n\r\nCopy and paste blocks and schematics do not correct the issue, lading me to believe its some mysterious block id error.  For now just crossing my fingers Mojang catches the bug in the client. "}}
