Player is not being ported into demon's realm on Kalecgos Boss in Sunwell Plateau

Kalecgos cast spell Spectral blast. The target is ported into realm(demon realm) and other players should click on the portal. But only targeted player is ported and others could not get transport into realm after click on the portal.

There were another iteration of testing with deleted cache. Could you please get it work so we can progress SWP on this Monday? THanks

1) Get heal, tank and another guy 2) Wait till get portal on target 3) Another player click on the portal 4) Nothing happens

After portal appears, guy who clicks without debuff on the portal should be transfered into demons realm. Proof: Here is the spell on wowhead https://www.wowhead.com/tbc/spell=44866/spectral-blast
