im waiting the version 6 i hate night time...... what are the new features??? im excited!!!!
That isn't night. Day/night cycles haven't been implemented. What you're seeing is a bug that the devs haven't been able to replicate, making it harder to fix.
I've made a few more changes in Version 6 to the way the game draws the ground so I'm hoping that will solve the problem. If not please let me know.
