I don't know if you folks are still working on this, but I thought you might want to know that I have a fix for the missing radar dish dice tower. I had a local saved copy of it and reuploaded it to Steam for my fork of drod's version, Imperial Assault 3D (Fixed)

There are a couple additional patches I made over there. One is a global find/replace of != to ~= (since Lua actually doesn't use the != syntax, but it ignores the conditional). And the other is commenting out the line
getObjectFromGUID('82f9d9').interactable = false -- dice tower

Because it's just plain broken and causes an error at load

This is so much more than just a new campaign. All the added downtime features, modular weapon system and the superbly written narrative make this more of full scale expansion that builds on the core game without losing any of the mechanics that makes it Imperial Assault. We had so much fun playing through this.

Fantastic campaign. Stayed true to Imperial Assault and Star Wars universe while also adding in some cool extra campaign mechanics.
