This mod is supposed to increase the capacity of vanilla inserters right? Do I need to start a new game to make it work because at the moment nothing happened when I installed it.

Perhaps there's a conflict with Infinite Technologies mod? Using infinite technologies I have stack inserter capacity upto 42. I installed this mod and it didn't change.

EDIT: I think it is a conflict with infinite technologies. I've uninstalled infinite technologies and this mod is working now. I found other mods to boost bot cargo capacity and battery capacity so I don't need infinite technologies anymore. Ignore this post. Thanks for your mod.
