I'm getting some missing art file errors every time I build this. It doesn't crash or anything, but my computer spits out a couple messages and the mouse won't interface correctly until I shift windows using crtl-alt-del and back.

I'll subscribe and give it a try at least. It really wouldn't make sense for it to work considering the trade route overhaul, but if it somehow does that would be quite powerful.

BNW removes the old Trade Route system entirely. It is likely not compatible. (But I don't have BNW so cannot test, sorry!)

I haven't tested it to make sure but there's no reason why it woudn't be compatiable with BNW

BNW Compatible?

Yeah I'd consider lowering the cost and more than likely will. In hindsight I'm not sure why I made it more expensive than the other wonders you unlock around the same time.

That doesn't follow from the balance other game effects have. Would you consider reducing its cost and -if you deem it neccessary for balance- effect?

I made it a bunch more expensive then other wonders you'll unlock around the same time on purpose

Whenever I unlock this wonder, it seems very expensive. Is it costed to scale with other wonders accessible through techs of the same level?

Ah, just like old times. :)

the wonder's unlocked by navigation

Sounds great. What tech unlocks it?
