Error in Calendar Post Update

I'm having the weirdest error in which the game will not load at all when attempting to load a family within a save if I have KawaiiStacie's Special Holidays mod,  but will load and throw an error if the mod is removed. Additionally, if the mod is removed, it will not allow me to create holidays on where i presume other holidays created by the mod previously existed. I have playtested loading in vanilla and it gives me no errors and no issues in the game besides being unable to create holidays in some calendar days, when i play with all mods except that mod it will load but gives me a lastexception error stating " [manus] holiday_service failed to handle on_all_households_and_sim_infos_loaded due to exception (AttributeError: 'NoneType' object has no attribute 'display_icon'), CategoryID: holiday_service:302", and when i played with only MCCC it did not give me any error or warning message but did end up creating that lastexception file that stated "<report><version>2</version><sessionid>8b6ff9a053b4529666a7dfda</sessionid><type>desync</type><sku>ea.maxis.sims4_64.15.pc</sku><createtime>2024-07-29 14:36:10</createtime><buildsignature>Local.Unknown.Unknown.1.108.335.1020-1.300.000.188.Release</buildsignature><categoryid>holiday_service.py:302</categoryid><desyncid>8b6ff9a053b4529666a7dfda</desyncid><systemconfig/><screenshot/><desyncdata>[manus] holiday_service failed to handle on_all_households_and_sim_infos_loaded due to exception (AttributeError: 'NoneType' object has no attribute 'display_icon')&#13;&#10;Traceback (most recent call last):&#13;&#10;&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\areaserver.py", line 130, in wrapped&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\areaserver.py", line 126, in finally_wrap&#13;&#10; File "T:\InGame\Gameplay\Scripts\Core\sims4\utils.py", line 157, in wrapper&#13;&#10; File "T:\InGame\Gameplay\Scripts\Core\sims4\utils.py", line 175, in wrapper&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\areaserver.py", line 383, in c_api_client_connect&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\zone.py", line 609, in do_zone_spin_up&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\zone_spin_up_service.py", line 1659, in update&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\zone_spin_up_service.py", line 292, in on_enter&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\game_services.py", line 38, in on_all_households_and_sim_infos_loaded&#13;&#10; File "T:\InGame\Gameplay\Scripts\Core\sims4\service_manager.py", line 454, in on_all_households_and_sim_infos_loaded&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\holidays\holiday_service.py", line 232, in on_all_households_and_sim_infos_loaded&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\holidays\holiday_service.py", line 177, in _schedule_all_holidays&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\drama_scheduler\drama_scheduler.py", line 510, in schedule_node&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\holidays\holiday_drama_node.py", line 391, in schedule&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\household_calendar\calendar_service.py", line 49, in mark_on_calendar&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\household_calendar\calendar_service.py", line 148, in _send_calendary_entry&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\holidays\holiday_drama_node.py", line 162, in create_calendar_entry&#13;&#10; File "T:\InGame\Gameplay\Scripts\Server\holidays\holiday_service.py", line 302, in get_holiday_display_icon&#13;&#10;AttributeError: 'NoneType' object has no attribute 'display_icon'rtim=0&#13;&#10;Client Session Time: 23.84&#13; &#10;Num Save Errors: 0&#13; &#10;Num Load Errors: 0&#13; &#10;Current Game State: 0x96d01090&#13; &#10;LoadingScreenActiveFlag: 1&#13; &#10;Origin Version: 13,257,0,5770&#13; &#10;Modded: True&#13; &#10;SystemInfo: Windows 10 10.0.19045 GPU: Intel(R) Iris(R) Plus Graphics igdumdim64.dll 30.0.100.9955, GUID: D7B78E66-C912-11CF-7B55-0929A8C2D335&#13; &#10;</desyncdata></report>

I apologize if this is messy in any way, i just wanted to include everything I could think of in order to hopefully fix my game.
