Well, I do have good and bad news.
The good news: there ain't any lua error left.
The bad news: there ain't any lua error left, everything is correct, yet civ5 crashes because of some bug inside of its engines only known.
And at that point there is nothing left I can do: there is no problem in Reseed's code. I could try to change things at random (literally) and see if civ5 suddenly likes that better but it would be an absurd, stupid and vain chase. I think you're encountering that random bug that makes civ5 crashes anytime you reload in-game : it is triggered as you add mods but any mod can trigger it afaik, not just IGE and Reseed, and it is not fixable anyway.
Sorry but at that point, the only thing that I can suggest are:
* Send those stupid crash reports to MS and Firaxis/2kgames
* Try to unistall every mod, delete the cache, mods and downloads folder within civ5's directory, then restart civ5 and wait patiently without doing anything on the mods page while civ5 downloads everything again.
I can't express my frustration : periodically an user reports that same unfixable problem with both Reseed and IGE, and there is just nothing I can do about it. Aside, maybe, of asking you after reseeding whether you want to reload right now or go back to the main menu to reload it manually from there.
After the trouble you went so far, I am sorry to be unable to help you. I can only thank you for your patience.
