I don't know if this is known but I've found something strange about the grid. It appears that the grid isn't aligning correctly.

image 2 is a screenshot of a exported map with lines to edited on top to show the misalignment

I think its because its mathmatically you cant really render it perfectly in such a low pixel size
i would still prefer if there was an option to overrender and have closer to perfect hexagons
cause for example maps in foundry drift after a bit (though maps like that would be way to huge and therefor not that viable)
