I haven’t been able to figure out what causes it but the press to respawn button switches between Mouse 2 and Space for me (I’ve bound jump to m2 and 2ndary fire to space) it accurately reports which button is supposed to work though
Random Respawn Button
Same for me, I use mouse2 for jump and space for sprint, and it randomly alternates between which of those I have to press to respawn. Bit annoying as I’m used to spamming one of them when I’m dead only to find out it’s the other one I need to be pressing this time. Also, as space = sprint, if I have to press space to respawn I have to release and re-press to start sprinting, rather than sprint right from the off as I’m used to.
Alternates randomly between Ctrl and Space for me. I have Ctrl for jump, and Space for secondary fire.
This is a bit annoying, also used to spamming m2 to respawn and then realising it says space 
Would be nice if we had the option to automatically respawn instead of having to press a key.
Guys could you try binding your jump key to JumpCmd in SGPlayerInputSpectator (as well as SGPlayerInputPawn) in ShooterInput.ini to see if this helps.
You can’t do it in-game and have to do it manually in the ini file which can be found at “%USERPROFILE%\Documents\My Games\UnrealEngine3\ShooterGame\Config”.

Did my fix in #6 work for you?
Don’t really understand what you mean Mustang, could you give us an idiots guide on how to apply this fix?
edit: don’t understand UE3 key binding but I found some lines that had “SpaceBar” and “JumpCmd” in them, which as I don’t use SPACE to jump I removed those lines. The game now tells me to press MOUSE2 (which is my jump key) to respawn, but sometimes it works and sometimes it doesn’t, i.e the message is now correct but the actual key you need to press to respawn still switches randomly between SPACE and MOUSE2.
edit2: not sure that was the case actually as other times I found myself not able to respawn at all regardless of what key I pressed, so I restored the original ShooterInput.ini and now I’m back to randomly switching between MOUSE2 and SPACE again.
