There is already a monster at (coordinates)

Get this error TONS while walking around new areas with hordes on.

game is trying to place zombie in place of other zombie but this place is occupied and this happen

The game should stop telling me about it. It doesn’t seem to actually hurt anything.

It sounds like you might have debug mode on? Hit ~ to toggle.

Any time the game gives you a debug message, it toggles debug mode on and leaves it that way. You have to turn it back off yourself.

Also highly prone to happening in fungal flowers, from my experience.

Is there really any reason to have it spam debug messages? Might be better if it was a debug message that only showed up if debug mode is already ON. >.>
