Whenever I run the world converter, it doesn't change anything. I run it, it goes through all the chunks, but then it comes up saying
"Done in [xxxx]ms
0 placed blocks changed
0 blocks in player inventories changed
0 blocks in entity inventories changed"
No errors given.
It is for sure a 1.1.4 world, as I have played 1.1.4 using it with no problems.
When I test it, I have things like 64 bat boxes in my inventory.
Please help.
