Disappearing closing character on new line

[MTBorg]

After a pair has been inserted and nothing but a newline is entered, pushing the closing character down a line, the closing character disappears until insert mode is exited. The issue does not seem to happen when anything is entered between the pair. I've tried disabling all other plugins and settings but the issue still remains.

My .vimrc:

set omnifunc=syntaxcomplete#Complete
set completeopt+=menuone,noselect,noinsert
set nocompatible
set autoindent
" set cursorline " This is nice but makes vim slow in some case
set synmaxcol=90 " Limit syntax highlighting to amount of columns (you might want to disable this if you're on a fast system
set colorcolumn=90
set nofoldenable
set foldmethod=syntax
set history=100
set hlsearch
set incsearch
set ignorecase
set laststatus=2
set nospell
set noerrorbells
set noswapfile
set number relativenumber
set numberwidth=1
set tabstop=2
set showmatch
set shiftwidth=2
set timeoutlen=1000 ttimeoutlen=0 "This makes visual blocks fast
set updatetime=100
set viminfo+=n~/.vim/.viminfo "Different folder for viminfo file (disable if not on linux)
