I've tested and at day 43 pixies stopped working. In the console I have every seconds (depending on the game speed) this message in loop :
[Error : Unity Log] IndexOutOfRangeException: Index was outside the bounds of the array.

The game is still playable (without pixies) but if you select the slave with the issue, the game froze and stop working. I had to ALT+F4 to close it.
Hope it helps because I love what you do on this game with modding and If I can help you in any way let me know.
