Some bad wall joins....

[rsf]

Hello.
Can someone take a look at this bad wall join examples.
The strange part is that sometimes they get fixed without doing anything (one time I just went for coffee and voilá...fixed :-S )
Case #1 is a join between an interior wall and a wall that is cut in the exterior one. The finish layers are wrapping I they shouldn't
The second case seams like a precedence issue. Sometimes streching the horizontal walls and moving back to furtherest face of the vertical one fixes this because the wall ends stay separated...well hope you understand. Even when I can make this the next time I open the project the wall ends returns to the snapped position again.
Any advices??
Thanks

By the way...is the size of this project reasonable??? It's just 5 walls!!! It seams it is already compresses because zipping don't help!?

Doing Save As.. with a different name reduces this file to 400KB. Save As... with different name often gives such improvement especially for small files. Explanation of why it is happening is somewhat involved and I am too lazy.
