Error while running event IndustrialRevolution3LoadersStacking::ir-entity-adjustment (ID 256)
LuaGameScript doesn't contain key item_prototypes.

I didn't realise this add-on had its own keybinds! Should be fairly simple to fix.

What isn't simple is Quality.. you can put quality items into the stackers can't you? Which means you can obtain quality versions of stacked items, which the keybind will need to account for... Argh!

EDIT: Okay I think I've got it now. One thing I haven't done is add quality to the little pop-up icons that appear above you (and I didn't do it for transfer plates either). The code for this is a bit fiddly and I don't feel like rewriting it all.

Thanks Shemp, always very active, I have a personal request for you, the transfer plates don't work on the logistic chests, would it be possible to activate them there too? It's convenient for assigning spaces to certain products or quality versions.

The transfer plates should work on them. The hotkey not working is a bug which I've now fixed.
