From log:
The given sprite rectangle (left_top=0x0, right_bottom=256x256) is outside the actual sprite size (left_top=0x0, right_bottom=128x128).
If this is being used as an icon you may need to define the icon_size property.
See the log file for more information.: tech_tree_plus/graphics/icons/tech/utility_armor.png; mods: tech_tree_plus
Prototypes using the sprite:
data.raw["technology"]["utility_armor"]
Fixed it for myself by changing icon_size to 128 on string 2241 in technology.lua
