stack of 100 units, regardless of the parameters

It very much does support bobs mods!

Are you sure you have this mod loaded?

Yes.

Maybe other fashions influence this and it starts to work incorrectly. Some items are adjusted.

Try disabling mods one by one until you find the one causing your issue. I can assure you this mod very much does work with bobs so something is interfering.

Looking at the screenshots I suspect it may be Big Bags or possibly that Russian looking mod listed in your 3rd screenshot. I can't read Russian so have no clue what that is though.

What about Bigbags fashion, that without it the result is one. A mod you couldn't read https://mods.factorio.com/mod/techno
Looking for a mod, then unsubscribe.
thank you

Alright that one does seems to override the stacksizes.

complete not compatible with fashion https://mods.factorio.com/mod/techno
Bob is not fully compatible either. tin stack is 40k and not 20k

My mod simply multiplies the original stack sizes. that 40k stack size is because the original stack size was 200 (your multiplier being 200) ... 200 * 200 = 40000.

I can add a soft dependency to that techno mod so that my mods multipliers are applied after that ones it might help in your particular situation.

Alright soft dependency to techno added in release 0.2.1, Love to hear if it works for you.

as well as poor compatibility with fashion https://mods.factorio.com/mod/Yuoki
the stack size for different items is different
for example: glass 20k, tin 40k, stone blocks more than 60k

Thanks

That is not a bug though ... as I said before this mod simply multiplies the original stack sizes. Yuoki's stack sizes are varied from the start.

Ok. Thanks

Thank you very much. All stacks of 20k.
