Something of interest in the Deepkin rules errata as well.
Page 94 – The Ethersea Change the final paragraph to: ‘An Idoneth Deepkin army can include up to 2 Gloomtide Shipwreck terrain features. After territories have been chosen but before armies are set up, you can set up the Gloomtide Shipwrecks anywhere on the battlefield, more than 1” from any other terrain features, more than 6” from any other Gloomtide Shipwrecks, and more than 6” from where any objectives will be located at the start of the first battle round. If both players can set up a terrain feature before armies are set up, they must roll-off, and the winner can choose the order in which the terrain features are set up.’
I wonder if this applies to The woods we place before the game starts as well or even the Nurgle forests for that matter? The important part being 6" from an objective. It would seem odd to penalize just Deepkin and not any other faction for beginning game terrain placement.
