IFrames Have Been Removed?

Hi, Hello, Hi. I have encounter a bug in which all iframes have been removed from the game by no fault of any procedure or thing inside my mod, when I export the mod and play it through the launcher all the iframes are there and but when i load it in Gradle they are not there and things like fire, lava, suffocating deal damage continuously but also only when wearing armor, which is confusing me very much, although from a test through a procedure the damage is still happening when the armor is not on but just does not effect the player which is also weird. not sure what this is but it confuses me to no end, if you have any info on how i could fix this please let me know
