projmake closes buffer when I 'close' errors

[Licenser]

disclaimer: I'm not 100% sure with emacs termenoligy so I might mix up window, buffer, frame and what not. so I'll try to put in some graphics :).

When the error view is open, and all errors are resolved the view is closed also closing the window (I think it's window)

To reproduce:

1. have errors

+-----------------+
|                 |
| my bad code     |
|                 |
|                 |
|                 |
|                 |
|                 |
+-----------------+

2. safe
3. open the projmake error console in a different frame

+-----------------+
|                 |
| my bad code     |
|                 |
+-----------------+
| projmake        |
| errors          |
|                 |
+-----------------+

4. be a good and fix the errors
5. safe
6. watch the lower window (projmake errors) close without my consent (and we all know consent is important)

+-----------------+
|                 |
| my god code     |
|                 |
|                 |
|                 |
|                 |
|                 |
+-----------------+

I also noticed that when the 'show error mode buffer' is active then projmake will also close random other windows until only one is left.
