How to maximise the stability of your 1.1 game

[Tellos Athenaios]

-Do any of the cheats, like move_character or create_unit cause bugs to happen if they're used correctly (ie not spawning units a faction can't actually recruit, or moving characters in settlements or currently laying siege to somewhere)? What about process_cq?
-Is there a maximum treasury figure, after which a faction becomes unstable if they've passed that number? I often add lots of money to the Eleutheroi faction.
I don't know about these.

move_character "character_name"

This is an incorrect line of code, but will "be accepted" by the console. Not so by the game though: it will render your 'agent' (the character this is invoked on) invisible! You can 'get him back' by (immediately) specifying a valid invocation of the cheat.

create_units [args]

Giving units a particular faction does not 'own' ('can't recruit by default') which aren't mercs in the true sense (for hire as mercs in the game itself) will cause a CTD if you try them on the battlefield. Reason: for a unit to work on the battlefield a faction must have a slot assigned on the model, with the exception of mercs - these take the special merc slot. So factions that can't recruit unit X by default will not 'have' the required code dealing with the model & skins. However, auto-calc appears to work out fine regardless (see Q.S.'s thread asking about this earlier). If you 'recruited' them yourself this way; your best bet is to immediately disband them.
