The problem was this: From a technical standpoint, the Goblin-Town expansion in 4.6 consists of a series of walls and wall hubs. Radagast the Musical had also created new, suitable models for the build plots of the stone Gundabad citadel, raising their own Gundabad banner. After a few minor hiccups where Gundabad tunnels would just vanish into thin air and the builders would reappear out of said nothingness and immediately start digging tunnels to Goblin-Town again, the AI was able to handle Gundabad just fine. The AI alternates in recruiting them, ensuring that it actually has access to all three orc realms. The first step of our solution then involved giving the AI two different builders, each of whom could only dig tunnels to either Gundabad or to Goblin-Town.

This led to extremely unsatisfactory, albeit somewhat hilarious, attempts, where the AI got addicted to building one and the same building as enthusiastically as if it were the finest pipeweed in the South Farthing. Neither did it try to build a Gundabad outpost, nor did it build more buildings from the completed Goblin-Town citadels. The next problem was that the Orkstadt AI loved to build Goblin-Town tunnels.

'How did you manage to build a Ransacked Mine within the citadel?' 'Veeery carefully!'
