Bug description
I get the following error, when running simulations in about 30° yawed inflow simulations:

forrtl: severe (408): fort: (10): Subscript #4 of the array FFDATA has value 36680 which is greater than the upper bound of 36679

I get the error both with YawDOF true&false. I can circumvent it with using slightly different initial conditions. The error is not wind speed dependend - on one mean wind speed, some turbulent seeds work, some don't.
ED NacYaw = 30 deg
SD YawNeut = 30 deg

To Reproduce

Steps to reproduce the behavior:

1. Compile with Visual Studio Professional 2015 and Intel Fortran Parallel Studio xe 2018
2. Run different seeds of turbulent simulations (Bladed-style wind fields, TurbSim 2.0) case with settings: ED NacYaw = 30 deg
   SD YawNeut = 30 deg
3. See the error

I am hoping that #578 fixed this issue. That update is in both dev and main branches.
Could you check to see if it is still a problem?
