Naga building models make use of texture animations for water, which is broken in 1.33 SD at this time. I will attach 1.32 and 1.33 examples of Tidal Guardian for comparison.

Note that this also affects the 1.32 model when rendered in 1.33.
This issue could indicate texture animations or some other part of the model handing code is no longer correct for these cases.
