hi i crash when i try to create the mapshot http://prntscr.com/v523no

Hello - do you know to which value you might have set tilemin or tilemax ? (if overriden, they are visible in settings/Mod settings/Per player)

Thanks for the screenshots, that's quite helpful. It seems I was a bit optimistic for the allowed values for "Largest tile size" (tilemax). Long story short, use 1024 at most for "Largest tile size". This is a limitation of what Factorio rendering engines allows to render at once.

For the details: zoom is calculated as rendersize / 32 / tilesize. So, with tilesize = 2048 (and rendersize = 1024), that gives us a zoom of 0.015625, which is smaller to 0.031250 (which corresponds to tilesize=1024)

For searchability: error message was "Error while running command "mapshot": Zoom has to be greater than or equal to 0.031250".

ok thank

Fwiw, I've fixed the parameter range to prevent the issue and added some logic to detect the problem (instead of miserably crashing that is).
