Starting with version 8.11, dead loads over openings did not accumulate properly, creating two sets of overlapping loads in load view over openings, with a load used for hold-down creation and Jhd calculation that is much too large. Therefore, there is too heavy a countervailing dead force at hold-down locations, and the Jhd factors that are calculated via 9.4.5.2,3 are significantly too small, as J_hd is directly related to hold-down force P. Both of these are non-conservative errors, and have been corrected.
