mysterious scroll

[marnix]

my version is (1.2.3) I got the scrolls from 1 Mist island 2 Helios sewers 3 koril cave 4 whirl island 5 nasca town 6 void gauntlet 7 fiery cavern

but in the cave where you put the scrolls in the stones there are 8 stones and on the insurgence wiki their are only those 7 places above is their a 8th puzzle if there is one where because now i cant get past the last stone in the cave
