Place animals in your Minecraft map, if they were lost with the 1.8.x update.
This tool will place animals in your Minecraft map, if there are no animals existing. This can happen to old maps after upgrading to Minecraft >= Beta 1.8.
It tries to simulate the standard Minecraft animal spawning mechanism. Spawning wolves is a bit problematic, they only spawn in forest biomes, but it is (IMHO) not possible to read out the used biome for a chunk. So this tool tries to figure out where a forest could be (where are many trees?).
Before you do this, PLEASE backup your Map. I could not see any problems, but just in case…
animalfix.py, select the directory of your Minecraft map and click “Lets do it!”.
Then you have to wait quite a long time. My map is ~ 50 MiB large and it took about 15 minutes to fix it (running on Fedora 14 with an Phenom II X4 965).
There is an EXE file for Windows (32-bit, should also work on 64-bit), so you do not have to download Python and tons of other software. Just unzip the archive and execute mcanimalfix.exe. Download: https://github.com/downloads/silvasur/mcanimalfix/mcanimalfix_win32.zip
