I looked on the forums and stumbled upon an interesting seed and decided to try it out. Firstly installed this on my server with the following details:
Type: Large Biomes
/tp -986 33 -2560 there should be a dungeon with a skeleton spawner. Instead, it was not there. I thought I would try it locally. Created a single player world on my laptop, with the exact same details, and at
/tp -986 33 -2560 there was indeed a dungeon.
At this point, I closed my laptop, and decided to go on my main pc to check out the complete seed first before I place it on my server again.
I created a single player world on my PC with exactly the same details as my laptop. I did
/tp -986 33 -2560 and there was no dungeon to be found!
Tried this back and forth on my laptop and pc and everytime the dungeon is there on my laptop, and not om my PC, it's driving me insane. For both PC and Laptop, exact the same:
[11:12:54 INFO]: Minecraft Launcher 1.6.11 (through bootstrap 5) started on windows... [11:12:54 INFO]: Current time is Apr 4, 2015 11:12:54 AM [11:12:54 INFO]: System.getProperty('os.name') == 'Windows 8.1' [11:12:54 INFO]: System.getProperty('os.version') == '6.3' [11:12:54 INFO]: System.getProperty('os.arch') == 'amd64' [11:12:54 INFO]: System.getProperty('java.version') == '1.8.0_20' [11:12:54 INFO]: System.getProperty('java.vendor') == 'Oracle Corporation' [11:12:54 INFO]: System.getProperty('sun.arch.data.model') == '64'
Both PC and Laptop eventually running Minecraft 1.8.3. No mods, no texture packs, all clean installs, clean .minecraft folder. Same account, same java runtime details.
Eventually I want to run the version with the dungeon on my server, anyone have a clue how I can achieve this.
Adding a little bit more info:
