Normal torches turn to bone torches

[Spriggan]

Whenever I go underground any normal torches turn into bone torches, even if they are already placed or I place them. It is permanent from the looks of it and it happens only in the presence of my character. It doesn't seem to affect any biome torch, only the normal one.

It isn't game breaking or even annoying, just wondering what mod does that and if it can affect my torch luck underground.

The only major mod I use is Calamity. Beside it, mostly qol mods.

Turn the torch god setting of next to your inventory.

I had the same exact issue and I found the problem. You are most likely using Fargo's Mutant Mod since you said you use qol mods. There's a setting in the mod config that changes torch gods ability to change already placed torches to match their biome, but I'm assuming it's bugged or something hence why they all change to bone torches. Find this setting and turn it off and it should fix the problem

I don't see it in the settings
