Problem combining TweakMod + premade map

[anacardo]

I've been experimenting with the TweakMod modmod which has actually cut out a lot of the instability associated with the 'KE huge ICE empires v1.0' presettled map. The only really annoying problem I'm experiencing is that the scenario is auto-starting with the 'ascending difficulty' challenge enabled, where the game ticks up a difficulty level every 50 turns. That is no fun at all and it seems like it should be a simple line-edit fix to turn it off, but be damned if I know how. Any ideas? Would it be as simple as inserting the correct tag into an .ini file somewhere? Somebody help me out pls.
