Altar of Sacrifice crash

It happens when I go to the last page of monsters, then try to change to another page. My last page only has 1 monster.


############################################################################################
FATAL ERROR in
action number 1
of Draw Event
for object obj_sacrifice:

Push :: Execution Error - Variable Index [0,-5] out of range [1,154] - -1.crits(100261,-5)
at gml_Object_obj_sacrifice_Draw_64
############################################################################################

stack frame is
gml_Object_obj_sacrifice_Draw_64 (line -1)

This may have something to do with it
