Fail to build on Half a series

[UnixNight]

Hello, I've been trying to get this to work on Trigun Remastered but it only seems to work on half the series. Here is the output from Episode 5

I have tried to set the nodefaultflags like I saw in a few other issues but It did not work. Any suggestions?
