Leap year simulation not running

Hello,

I’m trying to run a simulation with a TMY that includes a 29-day February. Upon checking previous threads, I edited the LB Analysis Period to set is_leap_year=True, and this changed the number of hours in the analysis period to 8784 but the simulation returned the following error:

Runtime error (AssertionException): analysis_period is_leap_year must match that on theCollection header. False != True

Traceback:
line 502, in _check_analysis_period, “C:\Users\Admin\ladybug_tools\python\Lib\site-packages\ladybug\datacollection.py”
line 782, in filter_by_analysis_period, “C:\Users\Admin\ladybug_tools\python\Lib\site-packages\ladybug\datacollection.py”
line 1391, in approximate_design_day, “C:\Users\Admin\ladybug_tools\python\Lib\site-packages\ladybug\epw.py”
line 196, in script

I also checked the header of the epw and it is set to Yes for leap year, so I’m not sure what the issue could be.
