[boskid][0.18.2] can't put half a stack of coal in steam inserters

[Deztro]

I've upgraded from 0.17.59 to 0.18.2 and started a new world.
I can't put in half a stack of coal into steam inserters (Ctrl+Right mouse), only full stacks.
As far as i can see it's only with steam inserters, not with other things.

Thanks for the report. It's now fixed for the next release.
