Summary0019584: crash after game loss: hovertext
DescriptionI was trying to test my changes to make the nanocaust keep chugging along after you died. I suicided my ark into the AI and then immediately hit some crashes:

This is because of the GUI being hidden when the "you have lost" text is shown. I plan on changing that, now that we're not using overlay gui mode for the gui. Now that that's in camera space, I can make non-gui things that are higher than the gui, and this problem will thus go away. Sorry about that, in the meantime. Unity chokes and dies when a control that is invisible tries to measure the size of text.

Fair enough. I was going to try to make the Nanocaust be interesting after the game ended like ovalcircle wanted, but I guess it will have to wait cause I can't test it. No worries.

If you want to make it not hide the GUI anymore, then give me a savegame right before death so I can get the layering right, then we'll be halfway there. You can start doing your stuff as soon as the not-hiding-gui bit is in there, and I'll get the display layering done after that as I have time.

* Because of some changes in the overlay camera hierarchy a while ago, the "You lose text" now shows above the GUI, which is what we've desired for a while.
** Thanks to this, we no longer have to hide the GUI after a game loss; the GUI should never be completely hidden using the methods that we were using at the time, because it leads to "hovertext crashes," among other crashes. The in-game hide GUI button never had this problem.
