Monster breaking after using touch event

[sprite_boi1O1 (Zpritey)]

I want to create a monster that grabs a random player and takes them to a cage where they trap them inside before going back out and continuing the loop.

The monster breaks after I use the touch event to see if the monster has reached the destination to drop the player in the cage.

(Problem occurs in the “Code” section)
