I've tried to get the investor ending but nothing shows, it just brings me back to the main menu. I was using Dondre as my partner and was able to get over the required point limit twice. first time I got just enough points in last round and the second time I had enough points two rounds before the final one. I didn't watch any of the scenes that came with getting all the golden pipes and in some rounds I got no golden pipes at all. I also noticed a bug that whenever I went to menu after a failure and played again, the pipes would fill at the boosted speed. it would go back to normal after spilling. It also still showed the message that I could boost the pressure.
