Hi, I'm back and I've finally had some time to take a look and it's... exceptionally weird. With the debugger I can see the buttons are all created but the HUD for some reason only shows the auxiliary buttons (toggle background, toggle surface split, toggle narrow view). Without the filter buttons, you obviously can't change to a different filter.
It gets weirder: if I use remote.call("YARM", "set_filter", game.player.index, "all")
, I get to see all the sites as I'm supposed to, and the list is very long (there are 120-ish sites) so it has a scroll bar -- the filter buttons are not scrolled off-screen! They literally did not render, or maybe they're rendering underneath the visible ones.
This might actually be a Factorio bug, and I'm going to report it -- the buttons exist as children of the mod_gui.YARM_root.buttons
container, which is a vertical flow, so they should be visible. However, I suspect Wube will not prioritize it highly, as this is a very modded game.
