This Version will patch from Version 1.6.6 through 1.7.1 to Version 1.7.2. Does that make sense? Install this Version and it will add all previous updates as far back as 1.6.7.
In other words, it will make your mod current no matter what Version you have installed from 1.6.6, 1.6.7, 1.6.8, 1.6.9, 1.7.0, or 1.7.1.
Version 1.7.2 (1.8 megs)
This Version will only update from 1.7.1 to current.
1.7.2 Update(1.2 megs)
I will upload the full Version of 1.7.2 later tonight.
