Rotations bug. 360º

[disla2]

Hello ,
The following strip rolls without issue when I request a time step that doesn’t generate a rotation that pass exactly through the 360º value.
The rotation boundary condition is built as 360 * t by means of an amplitude.
My advancing step is direct to force passing through multiples of 360º if I want.
Overall time periods of 1, 2 or 3 makes the convergence to fail while .98, 1.98 or 2.98 converges without issue.
I would say ccx doesn’t like the 360º value.(180º might have the same issue).
This .inp file runs correctly (converges) in Abaqus for the timeperiod 3 while it fails in ccx.
