broken temple/juatalotlis medallion

Hey,
My temple just broke. i was building a snake and had locked both the head and the tail of it. but when i closed the temple, two of my spymasters who was in the middle of the locked snake disappeared and have created this unreachable area.
Might be relevant: I had also placed a "fodder" spymasters right next to the first golemworks (from the entrance) that one of the spymasters inside the snake had assasinated to level up.
