Not a typo. The Minecraft ID for the Ocelot in 1.10 is Ozelot. I think it changed in 1.11 and the code should be correct.
changeling-master targets 1.10, not 1.12. changeling-1.12 targets 1.12. I'll put up a 1.11 branch soonish.
The intent for contributions is: Submit bugfixes to the earliest version in which it appears. However, I think the IDs are correct for the respective versions, so not a bug.
