Now I confirm that it has something to do with the network connection. If I disconnect from the network, there will be this error. If I connect to the network, there will be no such error. I can start the game
Why? Does mod have to connect to the network?
It seems this is the problem of Z2 mod. Its windows.xml contains links to the two online hosted textures. These two textures also are in the local mod's folder. But by default in mod's windows.xml the online path to the texture is active, not to the local asset. So, if you play Ravenhearst offline with no internet connection then you will get NRE red messages rain on the screen.
