I found the reason: the 4 chgrsign files are also empty. To solve the problem, I transferred the explorer's overlay to the charger. The result is like this lol :d
Yes, I thought that might be the cause, but all four livery options appear to be empty. :d I will reload the file and try again, hoping it will resolve the issue.
It's a really nice package, but I have a problem: the charger's coating isn't in the game. When I look at it in OpenIV, the coating is there, but it's not in the game. What should I do?
