Hi guys,
In order to update the world of our project we had to convert it using the World Converter, that is given by the Creators of the Conquest Mod.
This led to a problem with connected textures:
When we loaded the world with the latest version of the Conquest Resource Pack, the game crashes.
As we turn connected textures off, the game works, but obviously not the connected textures.
But these are vital for the look we want to achieve in our world.
We use a few mods:

-Conquest Reforged
-ArchitectureCraft
-CustomNPC's
-OptiFine
-Better Foliage

If there is someone, who konws how to fix this problem, it would be very helpful to give us advice.
