We have improved the procedure for calculating of long-term deflections in the Rectangular Slab Panel Design module.
Starting with version 2.6.04, the efective moment of inertia Ie is based on the minimum value for the X and Y-directions. This prevents cases where the long-term deflection could be underestimated when one direction was uncracked.
