Hi,
I use the Efficient Smelting - Full Belts and Full Fluids (https://mods.factorio.com/mod/EfficientSmelting) Mods and since there is an error, with your mod, it is not possible for me anymore.
Before you did the upgrate to 2.0 of this mod, it was fine. Please check this, since I whant to use both mods.
Error Messege:
Error while loading item prototype "factory-connection-indicator-settings" (item): 'stack_size' must be 1 when not-stackable is set.
Modification: Factorrissmo 2 - notnotmelon fork > Efficient Smelting - Full Belts and Full Fluids
If the error is not with your mod, let me know and I will contact the other one.
