Not sure if this is possible to change using the config as it doesn't seem to be place on any real block. Previous versions of this mod before it was called Firorize didn't cause this issue.
Without The Mod or with pre-firorize versions:

I have fixed it to default back to the regular fire/soul fire texture. I could also make it default to whatever you customized to go ontop of soul sand. What would you prefer it to work like?

Hmmm, I guess using whatever is customized for soul sand would be best. That should default to a blue fire by default then right?

Yeah its blue unless you change it, so ill default it to that, the patch should be released sometime today.

That would be perfect, thank you!
