VIM Package Fails Build if Renaming

[hooovahh]

So on VIPM 2017.0.0f1 I'm having a build that fails if I have some specific VIM, and the Renaming Convention is set. If I don't have renaming, or if I don't include this one VIM then things seem to work properly. Here is the error

 

 

And attached is the source and build spec. If the Filter 1D Array-VIM.vim is removed from the source, then the build works (renaming all the other files to have _Hooovahh as a suffix). Or if the Filter VIM is left but renaming is disabled the build is successful.
