Big thanks for keeping this up mate, they really made a cock up of doing it themselves.
A few bugs I've noticed with the GS implementation:
-Recommission nuclear plant doesn't show the age, nor the potential problems (I guess maybe the normal queue reads a separate table ?)
-Scrolling is only possible if you're scrolling from an available item (so a unit you can't build, or districts you can't build due to not enough population, if your mouse is on them, you can't scroll)
-The down arrow doesn't quite...work, for multiple units. It has to be on the..I guess, lower 3rd ? Of the button. This one is hard to explain.
-Flood gates showing up even if they aren't necessary/the city doesn't need them (they show up as 1 turn cost, you click on em and nothing happens)
-You can't queue up multiple repairs for the same district (workshop/factory/power plant). Well you can..but when 1 is done it gives you that ghost production thing where it says it's being built but still asks you to build something, so you have to select something else, remove the repair thing, then put it back in, and move it back to the top.
They're all niggles, rather than bugs, bar the nuke plant one. Although I kinda liked it, added a sense of danger
