when I go on a solar panel and I have the necessary resources to upgrade the function U does not work so I have to press each time the arrow which is painful
my colony 0.52
Check your key bindings in the engine settings. I've noticed that both "Show unemployed colonists" and "upgrade" option both have the same key binding, which is "u".
Thanks very much for including your game version and platform in the bug report.
I chose a new key the first time it works and then when I want to set a new key it does not work anymore
It's not working for me either. v0.52.0. Linux desktop client.
