[0.69.420 -PUBLIC#1307] Saendra's quest mob crash, again (Cannot read properties of undefined (reading 'hasStatusEffect'))

[Spidereggs]

On breaching the door at Anon's in Saendra's second quest and fighting the Mercenary Guard, the game crashes after the first round.
EDIT: Added the save that I forgot to attach.

Stack:
