Tiger, I am not sure how that is related. Perhaps make a new thread about it?
It built fine for me. However, be aware that you cannot have ( ) in the filenames of icons.
Asset [C:\Users\eliw0\Documents\GitHub\MobatGround Hill02\data\ui\vangineer\vangineersicon(2d).png] does not have a valid filename. Asset filenames must not start with numbers or contain spaces or dashes.
I am not sure what to say, other than search older posts in this forum to see if others had a similar error.
