After not getting desired change, I said to my self: Updated file might be somewhere in editor's directory and so went to find it. Fortunately enough, I was right!
And found updated files here:
D:\GOG Games\Kings Bounty Crossworlds GOTY\sessions\orcs\locations\m_atrixus
I was surprised when I saw more than one file has been updated for a simple position change! Here is their names:
m_atrixus.atoms.loc
m_atrixus.embryos.loc
m_atrixus.land.loc
m_atrixus.lus.loc
I copied those updated files to mods folder and ran the game. Fortunately now position of that stack is corrected, but some textures such as Texture of the bridge before that stack are missing.
Do you know how can I fix this problem?
