Cerberus chain glitch

IF you try to stoneskin the player who has the 'transporting' buff (carrying the chain to Cerberus during Re-awakening) the 'transporting' buff falls off and they're no longer carrying the chain. Not sure if this is intentional but there's potential for griefing or even un-intentional griefing. Tried it 3 times, 100% of the time the buff fell off as soon as stoneskin landed.

Edit: Spells successfully breaking chain so far

I'm pretty sure that's working as intended. Same mechanics is used for example in Copperbell HM when you feed the worm; the crystal will explode if you get hit by an attack, or you're buffed or healed.
