I can’t work with graphics very well, so I took the following files as a basis. If anyone has a desire to transfer and add a castle in the background, for the first time so far this option.
As I recall, it wasn’t there. I can’t find any old archives either. It wouldn’t be much fun if someone had to create them from scratch, enough exclusive parameters at the discretion of the mod author.
I don’t understand the point of your question. I have tested the mod, everything works fine. I did not see any errors. As for development, this is VCMI, everything is always being developed here.
