can you explain what is wrong I'm not sure whare your referring to?

I cut off the other icons. How smart of me.
If you activate alt mode the warehouse is not showing items despite having stone bricks in it.

Edit: You can see in the toolbar that I have alt mode on and no icon is showing.

are you referring to the icon scaling where the icons in the warehouse look bigger if there is less in there if so the one in your picture is the base one from angels mod and I have confirmed that doesn't work with the icon scaling I think angels missed adding it in his code.

there is no icon at all

I can see the stone brick icon in your picture its just very small on the buffer warehouse

Wait you are right but that is literally as big as a termite. Can you make that bigger?

angels needs to fix on his end he forgot to add the buffer warehouse he added to the mod options for the icon sizing.

angels needs to fix on his end

You added the buffer warehouse not him.

he forgot to add the buffer warehouse

It was left out by design IIRC

he added to the mod options for the icon sizing

you can just look what the options do and replicate it for the buffer warehouse and listen to the same setting.

well in the .17 updated he added the buffer warehouse I only added the mk2-mk4 ones

Angels fixed this in 0.4.1 that came out yesterday
