The above code is what comprises the end of my .vimrc file. This function use to work but after some updates (either YouCompleteMe or UltiSnips, unsure) the only time these work is when I first open vim in a directory and then open a file from there. I think it has something to do with the autocmd, but to be honest I don't know where to even start. I've tried changing the autocmd event to BufRead but, unfortunately, that made no difference. Any help is appreciated, thanks!
EDIT: If you think there is a better place I could post this question or you need more details, please tell me! I'm happy to help.
It seems BufEnter runs before VimEnter. This is a problem since SnipMate puts up its mappings in VimEnter. So the very first buffer has the SnipMate mapping instead of your custom one. And when you switch to a new buffer the autocmd run again putting the mapping in place for the new buffer.
To fix this just make the BufEnter mapping a buffer local mapping. This means that the mapping won't get over written by the SnipMate mapping. And the buffer local mapping has precedence when vim looks to run different mappings.
autocmd BufEnter * exec "inoremap <buffer> <silent> " . g:UltiSnipsExpandTrigger . " <cr>=g:UltiSnips_Complete()<cr>"
