Found a weird. (Browser version btw)
Got my first new universe.(Love how the constants are changed instead of having arbitrary upgrades like other incrementals)
I changed the cost the mineral value upgrade(q_MV) to 1.55 but the upgrade price still went up by 1.9 but after closing and re opening the price was back to what it should be.
price was 100. bought and it went to 36x something(probably 361) closed reopened and price is 240. then 372 then 576 then 895. So it's using 1.55 now.
Then, I'm also not receiving any Exp for building Extractor or power plants. upgrades give the expected amounts and Storage construction gives Exp too. I did change q to 1.3 so extractor costs 45
