In Deadly Monsters 1.9.0 I am noticing time reset to Day 1 when I am hit by Haunted Cow. This is resetting my progress on Hostile Worlds: Invasions and making the mod trivial to cheese. I didn't report earlier because I didn't notice until after installing a mod that allows me to see the current day.

Using the Sunlight Drop also seems to change the day to Day 2.

I used Time HUD 7.3.1 to see what day the game is in, but originally was using Better HUD before I ran into OpenGL errors that forced me to stop using it until I can locate what minimum conditions I need to report that.

You're absolutely right, I completely missed the other two cases of time changes. Hotfix coming soon!

Oh wow you even factored in doDaylightCycle gamerules in your logic. Can't wait to fear haunted cows even more than I already do!

I bet! 😏
