I've tried a new world (done using the Von Neumann mod) and I've received this error (you know, I hope, where to place the underscores that the forum hide):

Decu/control.lua:1: Decu/maps/cave/core.lua:2: Decu/maps/cave/surfaces/cave.lua:179: '}' expected (to close '{' at line 177) near 'copper'
stack traceback:

After that I've tried a new freeplay world and I've got this:

Decu/control.lua:1: Decu/maps/cave/core.lua:2: Decu/maps/cave/surfaces/cave.lua:179: '}' expected (to close '{' at line 177) near 'copper'

I have to note that I was creating an Island new world Using this setting (add 3 reversed <<< at the begin of the code, because the mod forum system salculate it as a sort of quote. I've left just one of them for let you see how it work):

If you want I can try without any other mods and do few tests for check what of my actual mod is causing the problem, if it's not a your code problem with Island setting.
Waiting for instructions.
Thanks for your work.

I've received a similar error, but different, deactivating your mod, then I've to tell that I've installed recently few scenario mods for try new ways to play.. Actually I'm doing tests deactivating many of them...

Hello, try now (factorio 1.0.0, mod version 1.0.5)
