Papyrus SLAX error

[𝔏𝔢𝔰𝔱𝔞𝔱 1627]

As the title suggests, I find a Papyrus error related to SLAX. This error causes CTD. How to fix it? 

If it can help, the error occurred immediately after completing the "Tower Bannermist" mission . I assume the mistake only started because they were all dead 

 

Spoiler

ERROR: Cannot cast from None to Actor[]

EDIT

 

Here, however, there was no one besides me, neither creatures nor NPC's
