Vim - Session management issues

Question

When I save and load a session (with split, vsplit and a different file) in Vim (or Gvim) with :mks and :source, or with a session manager plugin I can't load what I saved.

For example :

======= What I save ======

:mks ~/.vim/sessions/Session.vim

 —————————————————————————
|  1   |       2          |
|      |——————————————————|
|——————|                  |
|  3   |          4       |
|______|__________________|

4 differents file, 1 vsplit and 2 split ( different height ).

======= What I get ======

:source ~/.vim/sessions/Session.vim

 —————————————————————————
|  1 |       4     |  1   |
|————|             |      |
|    |_____________|______|
|  2 |       3     |  3   |
|____|_____________|______|

Two files ( 1 and 3 ) opened twice. Order change. Split and vsplit size and position are not the same.

Does anyone know why this happens? It's very painfull to manage sessions with things like that.

-> vim --version

Answer 1

Okay, I found the evil plugin. It's MiniBufferExplorer.

I tested without all plugins except for MiniBufferExplorer and I get the issue. I'm still not sure why though.
