Came across an odd bug earlier, for some reason some tools are not being shown if they are in proximity for crafting purposes. This happened after I updated from 0.C-19849-g1b41747 (tiles) to 0.C-20170-gaf4179b (tiles).
In this first pic you can see that the recipe doesn’t notice there is a HP&DS for the tool requirement, yet does for the charges it needs for it.
As you can see the HP&DS is in close proximity, I also have a Food Co Buddy 2 squares away.
As you can see in this image it says I have no pair of metal tongs, yet I do a pair in proximity as is shown on the 2nd image.
Not sure if this is of any help but the two tools shown on the 2nd image were newly aquired in 0.C-20170-gaf4179b (tiles), yet the other tools weren’t.
