It seems you hit the hard limit for total cursors. When initializing after restarting the game, it's causing an IndexOutOfRangeException, hence only 1 cursor showing.

An update should be out by some point tomorrow addressing this issue.

Thanks for the catch,
NullReferenceException

The cursor limit has been removed in the update released today. I had to re-code the cursor system, but it should now (theoretically) support as many cursors as your computer can handle.

Once again, thank you for bringing this to my attention, it's greatly appreciated.

Regards,
