I try going into another world, and I egt these errors: In Game: [Error] The level couldn't be loaded Or: [SignPortal] World '<worldName>' not found. Console: Invalid level.dat, see also: http://i.cubeupload.com/A3eNJ2.png Plus, when will the missing Blocks be added? I need Elytra, Purpur Blocks, Beacon, Red Sandstone, Doors, and all the other missing things for my shop!
You probably edited a level.dat file without a proper nbt editor, or you messed something up in the file.
If the level.dat file is messed up, you might be able to fix it by correcting the level.dat file using a proper nbt editor, such as NBTExplorer. They will be added when the PocketMine developers are able to implement them. MCPE updates way too fast and often to do everything instantly.
1. OK, I'll try. 2. Why does it take months for them? There's around 1 and a half months time until the next updates.
to No. 1: I cannot open the level.dat, it says: One or more selected files failed to open. What shall I do now? Is my whole server lost?!
You might not have done it correctly then. Is the LevelName the same as the name of the world's folder?
Yes. I tried opening the level.dat again, and it showed me strange chinese symbols, like this: Code: 謟ࠈ⨲壕敬敶2免湁䄓퐐ᵨ妼胋Ϡᯊ斈爃�Ȗ瑎�죶㎳馫䝙㜋섞㠗胳鄉䡲赲췝餦䵣畗啵适潀Ƅ␅卡䤘饎餠ྡྷ㖟⒖쐁뎗闓䇪葿勥ѥ╻ꁠઌ딊䗺げ蹫�䅬Ｄ붼讛昉Ⲵ蛳铆챃蓇炡䗤ﴄ㤝겯≸衠�ϣ斛䟙燯䁆⇟摯ᆇ㛽鸈爭㘼꫟䁒䆼匧࣫辺곯褱罡㭊鿒妐捻ᥴ疫㼓ꪪ捊른䌦茎덵뀼張뒧彟⼱老ؘ㶙㢚ꭅꬦૠ奢ཀྵ퇭�⇐뒉ꥨ淒ഇ嶤䴪朣�썡�翬㜢ዜῥ軌�愨蕯㏚�쇔麡뚱凗ꕞ汭듯띍⊳엤閃툗畲굚䲠딵螚魓懲嚒䷀렮駒⤙薿쟻홍럩齹賿뗴냭៩î豖킈ɕ
You have to use an NBT editor to open it. You can't view it as readable otherwise, as only the computer can understand it then.
With Notepad, I saw this in the editor: LevelName world Now I changed world to another name. Plus, there werre some strange symbols between the letters/words, but I didn't change any of them.
Well that's your problem. Editing the file with notepad corrupted it. Notepad is only made for regular, plain text files. I'm sorry, but unless you backed it up before, than your world is probably lost. Please correct me if I'm wrong though. I definitely don't know of a way to fix it.
But it always (really always!) worked before! I always chanegd the LevelName in the level.dat and restarted my server, it never destroyed my world. But why did it exactly happen now? It always worked before and this time it didn't!
I fixed the problem! This tutorial saved my server – I got a level.dat file from my Minecraft Windows, and it now works perfectly. Only the spawn point changed and I needed to find the real spawn. But next time I edit a level.dat, Ill better use the NBT editor.
