Comment 8 for bug 1807699

Hi,

I actually do not reproduce "the same error as before" but another one:

           7 > 6 -5 color 2 > 3 -3
 failed for ipartupdate. Please retry without MLM/default dynamical scale
STOP 3

Which is due to the fake treatment of the 4 point interaction that is not compatible with
the mlm merging/default dynamical scale choice.

I then change the dynamical scale choidce to "3" (HT/2)
and it went trough without any issue:
