Please can I encourage you to all download CUP_terrains_core and CUP_terrains_maps as soon as possible. They are large downloads and will be replacing AiA.
We're being forced down this route faster than we would have liked due to inconsistencies in the way that PlayWithSix applies dependancies to the maps we use.
I suspect we will be forced to move over to this new format within a few days if not sooner - thanks for your understanding.
Note: AiA_TP will become redundant, so don't worry, you will get that space back as soon as we can ditch it.
