Some buttons behave oddly. The crafting x1 x5 x10 buttons flicker on mouseover and will usually fail to respond to my click. The intercept button also rarely works. Everything else seems to work fine.
The sound for raising the tech tier is horrible.
I am playing in Chrome on PC.
I cannot find the action "Insert Circuit Board" leaving me with very little to do but wait for science on that tech level and the next.
On the crafting button flicker and missed clicks — the x1/x5/x10 buttons are a known issue. A fix was just shipped for the action buttons (same root cause: UI rebuilding while you're mid-click), but the crafting buttons weren't covered by that fix yet. It's next in line. The intercept button is likely the same problem.
Tech tier unlock sound — noted, will replace it.
"Insert Circuit Board" — Could you say which tier you're on and what building or tab you saw it mentioned in? Circuits are crafted items (Assembler or manual crafting queue) rather than a manual action — it's possible something is referencing it in a tooltip or goal text that isn't matching the actual recipe name, which would be a bug worth tracking down.
Working on a fix will be available soon.
