This Mod change all Recieps of the Science Bottles. But it is not compatible to Marathon. Maby you can change this ?

Strange. I am playing with Science Cost Tweaker, Full Bobs, Full Angels and Marathon and I have no problems.

Could you elaborate as this mod specially does not change any recipes to the Science Bottles that I know of?

If i play without Science Cost Tweaker i need with Marathon for each red Bottle 40 Copper and (i think) 10 Iron-Gearwheel
This is very much for one bottle.
But if i use the Scince tweaker the cost of the Bottles are normally if i play whith the Recepts from Scince cost tweaker. They doesn´t be more expensive.
A red Bottle need in Marathon with Scince cost Tweakter 2 Iron and 1 Copper. Nothing is Chanced. This is the Same as without mods.
In config.lua of scince cost tweaker the Option ScincePackConfig is chanced to Bobsmods.

Sorry, but my English is not so good ;-)

Well, this is just meant for Angel's and Bob's Mods, not Science Cost Tweaker. I believe that you may want to adjust the config of that mod.
