Failed to load mods: The given sprite rectangle (left_top=0x0, right_bottom=256x256) is outside the actual sprite size (left_top=0x0, right_bottom=128x128).
See the log file for more information.: escape-to-space/graphics/technology/energy-data-disk.png

This is in Factorio 2.0.76 with no other mods aside from Escape to Space's dependencies.

Try with the new version, i adjusted the sprites size.
I'm a little bit confused tho, in my local playtest the game starts without any errors. I'll try the modpack on a different machine

If I resize all six data-disk.pngs and chemical-stager-icon.png to 256x256 (I think that was all) the game then loads successfully and I can start a new game.

Hm okay, i'll put icon_size checks in the to-do list. Thank you for downloading the modpack!

At a wild guess you have a right-size version hanging about locally which doesn't end up in the shipped ZIP.

That could be possibile, i think, but that would also be strange. I directly compressed the version that i use (i like developing directly into factorio mods folder)
