[Rseding91] [2.0.7] Crash when generating preview and quickly pressing "Play"

[LaNc3Ic3]

For reference, only base game is enabled.

1. What did you do?
   1. Singleplayer -> New Game -> Freeplay
   2. [In quick succession] Preview -> Play
   I attached a downscaled recording to demonstrate the issue.
2. What happened?
   Upon pressing "Play" after pressing "Preview", game crashed but produced a dialogue on next steps to take.
3. What did you expect to happen instead? It might be obvious to you, but do it anyway!
   I expected the game to load me into the newly-generated world without any issues.
4. Does it happen always, once, or sometimes?
   It always happens. however, I noticed that you wait maybe a second or two after pressing "Preview", the game loads in as intended. Maybe it's something to do with the preview not being fully generated yet?

[edit] Okay so, after a bit more experimenting, it turns out it doesn't just crash by following the above steps - it might crash as long as you do anything with the preview open. For example, if I refresh the seed enough it just seems to eventually crash. I also tried closing the preview prior to changing map generation values and sometimes reopening the preview would cause the game to crash.

Thanks for the report. This is now fixed for the next release.
