<br>
It seems that, in one of the latest changes, I unintentionally left<br>
out a code line where GRASS was actually being called. I was getting a<br>
bit crazy wondering where the error might be and why GRASS7 was not<br>
working in the latest release....and finally found out that the reason<br>
was that. So, in short, Processing was not running grass when running<br>
a grass7 algorithm.<br>
<br>
I have added that line back and it should be fine now.<br>
<br>
If you can install the current master version, please test and let me<br>
know if there are any issues or it is working correctly as before.<br>
