What is it with new shipsets?

[Fyron]

If it is script related, you have to get the source, update it with whatever changes were made that break the scripts, and recompile. If you can't get the source, the mod is forevermore dead in versions past its release. Otherwise, you just have to trawl through the data file errors the game spits out, fixing them.

[Captain Kwok]

Most shipset authors just copied and re-name existing stock AIs and stock them in their sets. So there's no harm doing the same to bring them up to the latest SE5 patch.
