AlreadyRunning error after the first run at NLO

Hi Marco,

I do not reproduce the error.
Did you edit the card between the two runs?
Do you have a debug file?

I guess that the issue is that the cards are updated (in a way) but that the code does not launch directly the handling of the card and that this one is trigger via the compilation of the Source directory.

Cheers,

Olivier

yes, I change any parameter in the run_card, for example.

This is the debug

Command "launch NLO" interrupted with error:

Hi,

I have tested a fix in 3.5.2 but this is not something that is easy to trigger (I did succeed to trigger it once and not anymore since my patch, but not 100% sure what is going on)
