Some months ago (before last update) I was able to get negative outputs from this command, but now it just prints positive values and no negatives... All negatives values are now "0".
This happened when applying a cyclic loading to elements (truss, fbc, etc) to calibrate buckling. Now I cant plot pushover curves the way I did
Any idea what could have change?

Good Morning Prof.
Attached is a simplified example, everything works fine in tension (where the loads have the same sign of the displacement) but when the loads should became negative, the load factor goes to "0".
I was able to show the compressive portion of the curve when I use a negative load for the negative displacement, but in that case, like a mirror of the previous case, the positive values of the loads give me a loadfactor of "0".
This is an older version of what I do now but none of them works now
edit: maybe my problem is not about the loadfactor command itself. I replaced it with nodal reactions to see the actual loads and for some reason the same happens. I tested with elastic beam-column as well. The same.
Thank you in advance!
