The selected starting position not showing seems to only be when you start the game without selecting a specific player color. Or something along those lines; selecting a color manually in the lobby can let you get around it temporarily, but we obviously need a better fix longterm.
The tabs for the buy/tech buttons being unreadable is a known issue.
None of the control nodes were removed, so it's some sort of display issue. Might be related to the display order issue from your screenshot, not sure.
Thanks!
