Thank you

got the same error

Can it do something with Factorio Standard Library dependency?
Or its Ion cannon error alone?

This can be fixed by adding this line before line 416 on prototypes\entities.lua

yuge_crater.animation =
{
width = 110,
height = 90,
frame_count = 1,
direction_count = 1,
filename = "base/graphics/entity/scorchmark/small-scorchmark.png"
}

So the completed block will read like this:

yuge_crater.name = "enormous-scorchmark"
yuge_crater.order = "d[remnants]-b[scorchmark]-b[yuge]"
yuge_crater.animation =
{
width = 110,
height = 90,
frame_count = 1,
direction_count = 1,
filename = "base/graphics/entity/scorchmark/small-scorchmark.png"
}
yuge_crater.animation.scale = settings.startup["ion-cannon-radius"].value / 4
yuge_crater.ground_patch.sheet.scale = settings.startup["ion-cannon-radius"].value / 4
yuge_crater.ground_patch_higher.sheet.scale = settings.startup["ion-cannon-radius"].value / 4,

"Base" needs to be with double underscores on sides. Reason it does not display here, its the code to make font bold.

But it works now, thanks Bellicosity

does the
[code] tag not work here [/code]
?
(this was a test)
-edit: I guess it doesn't... that's poor design choice imho.

Ah yeah, the fix above worked I think. I made the change to a headless server and it seems that clients still download the file from the mod portal here, is that correct? Is there any good way around that?

I've decided to just roll back to .17 for now. Don't want to bother with distributing a custom mod to everyone that connects.

That fix is working for me. Thank you! (don't forget the double underscores)

I have included this fix in v1.8.1. Thanks guys!
