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=64x64).

I am sorry but it is not reproducible for me. What factorio version are you using and are you using any extra mods?

Hmm, sorry, now I rechecked with steam version and error is gone.
I play a lot of mod packs with standalone (2.0.68 same as steam) and it first trouble with it. And first time checked without any mods.

I dont think it's related to bad files. But try to reload full fresh standalone game and also compare settings with steam.
And write here and onto bug tracker if that don't related to my game instance.

First, sorry again for false reporting. (Your mod first got trouble with my game launch method for 5+ years...)

I can reproduce the error, it's related to my method of running the game for multiple mods.
I think it's related to the game engine, but can't determine specific factors and because it's affect only custom game configs like my one, so I would't report it to forum for now.

And if you are interested how it works:
I love to try a lot of mods, and don't like when achievements drop etc and also having some game settings diff. between mod packs.
Perhaps I create(copy skel) subfolder for every mod set. Its contain start.bat running Factorio by relative path and modified config setting mods and setting folders to this subfolder.
By the way, I have a lightweight folder only with mods and configs and can run it easy and independently, but still have only one instance of main game files and can update from main game folder.
Its works with hundreds of mods, and I have no idea why its broken by your mod. May be the engine uses a diff. size check method when using relative paths this way, but I see no issues with other mods before.
Changing icon_size = 64 in Your mod fixes the problem, but obviously brokes the icons.

Thanks for the in depth response. Yes, it seems to be related to your way of running mods so I won't bother trying to fix it.

I am not an experienced modder, I am just trying shit and if it runs, I upload it. So it doesn't surprise me that this breaks the mod. I imagine that other modders actually knows what they are doing and handle icons in a more robust way than me. It is probably some icon size thing.

I reported bug to forum, it's marked as duplicate and I checked it with Your mod.
It's really error with mod. (and bug cause sometimes to ignore it by game)
You can reproduce by removing crop-cache.dat from appdata factorio or standalone factorio dir.
I got this error, because don't launched version of game before installing Your mod. (But if engine bug get resolved, I thought You also get same error with std setup)
