What's this?

Happened when I hit the 'end turn button'

That is the regular 'm2 has found an error' message - Gig style. The map download lacks too many files to be playable.

so how can we let it work ?

[Gigantus]

The map download is simply there to give a 'hands on' impression of the mod, there never was an intention to make it playable. The present state of the mod where I took it out from is over 1GB, picking out the necessary files to make it work would be time better spend on continuing working on the mod.
Rest assured that the complete mod is working fine so far.
