Found it. u were right, my apologies for wasting ur time, ill go ahead and close this, it was a mod called anticreeper I don't remember installing...

No problem, glad you figured it out!

Looks like Anti Creeper causes issues

"Caused by: org.spongepowered.asm.mixin.transformer.throwables.MixinPreProcessorException: Attach error for anticreeper.mixins.json:CreeperEntityMixin from mod anticreeper".

Maybe the mod has a different name, not sure then

i saw that. i only have one remotely creeper-related mod and thats creeper overhaul (makes creeper variants)

I guess it could be one other mod of mine, it splits mob greifing into 4 categories, one of which is hostile mob greifing, which is on (turns off stuff like enderman picking up blocks and creeper explosions), but those are the only mods remotely creeper or hostile mob related that I have
