Got a minor issue here, one I wouldn't call a bug but..
So I like to play with peaceful mode on toggled on to start with, till I can actually get a comfortable, basic base and set up going, and get an idea of how I want to build outwards. It's especially important when I'm trying out new groups of mods, since pretty much every major mod set is gonna do "things" to the recipes and progression that you have to figure out all over again. Later, I toggle it off, and let things get 'Fun'.
My issue here is.. Rampant spawns things that attack my base, including early on (only delayed by the 120 min timer), when I 'm far far from ready, and still usually going, "Okay, now what the heck did they do to my iron and copper progression here?". And it's usually -not- small attacks either. Usually involves having to respawn a dozen times or so to get them cleared out. Then spend a bunch of time finding and repairing and rebuilding.. and then it's close to time for another attack. This is where my actual issue comes up. As best as I can tell, rampant's additions do not respect the toggle-via-console peaceful mode method, probably due to the faction being involved. So for me, it becomes unplayable. I'm wondering if there's an easy enough way to tweak it to fix that.
As noted, this is more an issue with my play style interfacing with the mod, -not- a bug, not a 'oh gods, fix it nows!'. From what I've seen, you've put together some really good and complicated work, I'd just love to be able to enjoy it my way and not have to cut it from my list of stuff. :)
Anyways, thanks for the time and the hard work!

Let's clarify. Are you switching the biter to peaceful mode with the "rampantSetAState" command or "/c game.player.surface.peaceful_mode = true" or something else?
Did I understand correctly that there were no attacks for the first 2 hours?
I guess in this case I need a save to see the situation clearly

I'm using "/c game.player.surface.peaceful_mode = true", and the first 2 hours of no attacks are due to the handy mod setting you added from someone else's request. Lets see.. That'd be mod options -> map -> rampant, fixed -> Duration of the peace period (at the beginning of the game only), with it's maximum setting of 120 minutes. I'm thinking that perhaps the easiest way to handle my silly problem would be to increase the maximum setting quite a bit.. but then I'm all about easy solutions. :)

I think it's worth using a combined solution:
1. Increase maximum peace period to 10 hours
2. Since this will only have an effect in the new game, then add the command /RampantTruce NNN, where NNN - minutes.

I will add it in a new release. However, the release is not expected until a couple of weeks later.

Sweeeet. Thank you very much! And no worries on release time. I'm more than happy to wait, and continue chewing through my crazy backlog of games in the meantime. ;)
