Bug with Imperial Guard Enginseer unit + Forgeworld

[Jrandom]

With Forgeworld as allowed in the list, the player is unable to select the "Trojan Support Vehicle" as a dedicated transport for the Enginseer HQ choice.

Imperial Armor Volume 1, 2nd Edition (2012), page 232, gives the Trojan as being able to be purchased as a dedicated transport for the Enginseer.

Additional info: When a selecting the "Trojan Support Vehicle" as a unit upgrade for "Heavy Artillery Carriage Battery" or "Field Artillery Battery" (which are both chosen from Heavy Support), the list composition shows that a unit has been added to the Troops selection. Adding models to a Heavy Support selection should not count as a Troop selection for Roster Validation.

Imperial Armor Volume 1, 2nd Edition (2012), page 188 for the "Heavy Artillery Carriage Battery" and page 198 for the "Field Artillery Battery".
