I am also having an issue with this on 0.16.51 but the error is with stone.png and causes the mods RSO, YARM, NoFluidsToMine, BobOres, FlareStack, Liquid Science to need to be disabled. because of bobores stone.png icon size property is outside of sprite range.
0.16 versions of the mod aren't being updated anymore. In theory, nothing should error about icon_size, because nobody should be using larger size icons in there... The only exception would be if someone else is also changing the icon if they're still working on the mod, and integrating some 0.17 updates into older versions.
My only real suggestion is to go ahead and try Cryforce's fix.
