Suggestion and Feature Request

[Drakarys1402]

Right, I've managed to set up a custom campaign which works. I've moved Rome and "Parthia" to their relevant positions around 360AD. When I tried adding Sassanids as a playable faction in desc_strat (replacing Parthia for faction count) just to check if the faction logo would change to show a Sassanid one. However, it didn't and it actually didn't show any factions in the list below the Sassanids. Is there some way of solving this? Do I have to give them a full entry on the desc_strat in order for it to register as a faction? Just type as if I am modding the vanilla BI desc_strat and it'll do the rest to add Sassanids and W/R romans?

edit- Had a go trying to add the Goths into the game. Deleted macedon. Copied and pasted the strat entry from vanilla BI, added as a playable faction, made sure armies put in correct place on the strat map and deleted any rebel armies or other versions of the settlement (its the same entry at any rate). Didn't come up as a playable option and the mod won't start. Do you have any ideas what the issue might be?
