Hi
First of all, thanks for recreating SB in 2.0, I have been waiting for this. Just wanted to ask before I start a new run:
How finished is this mod? Is it mostly done? or like a beta still? I know that the mod version is above 1.0, so it should be good, but I just wanted to ask first.
Specifically if played with the entire pack.

Further: is the pack viable with 2.1 or are the mods not ported yet?
I am away from home for some time, so I can't check

I only uploaded the mod after my first playthrough. So it is very much playable. But early game is still very slow and a lot of people complain. So I am still very much at balancing things. There are Settings you can change to speed things up.
I already included a lot of things in the 2.1 version that I didn't include into the 2.0 version. But I'm backporting them at the moment.
So it is 1.1.4 version for 2.1 is at the moment the more playable than the 1.0.5

In the modpack I tried to stick to things that are 2.1 compatible or asked people to upgrade them. So this is definitively no problem. All dependencies that are not ported are very much optional. (And since we have optional dependencies it will work perfectly fine.)
The only things that are kind of a little problem are:

• Recursive Resource Calculator is not at all needed especially if you have the much more powerfull helmod that is also included.

• Configurable Pollution Absorption is not compatible with 2.1 but it also doesn't do anything until you manually enable pollution. If you do that be prepared that the game will need a powerful CPU.

• If you install for example cargo-ships it will automatically install Cargo Ships: Oil Rig which will disable SeaBlock. This is very much a bug in factorio 2.1 and not in the mods. But it affects modpacks a lot more then other mods. So make sure that you really enable all the things you want to have and disable all the mods you do not want to have.
