No way to get rid of an owned upgrade?
yield -1 myupgrade
I've troubleshooted every way I think I know how. For example, I'll have
and it'll 'do something' and it'll drop mybuilding and output "1" in the toast, but won't affect myupgrade. Not 100% sure this is a bug as I may be doing something wrong, but it sure looks like it and I am pulling my hair out trying to figure out how to unown an upgrade I've already earned
