I wish to help you. I’ll pretty soon be graduated in engineering (in I.T.) and I’ve worked as an intern at Ubisoft. I know neither Lua or ERM, but I know a bit about C++, math, IA, and reverse engineering.
(By the way, I read “Ubi has no bugtracking system” : that’s wrong, or maybe in their smallest studios)
I think my first step will be to dive into your source code see where I can help.
btw I’m French (I might help with translation as well)
