Expedition Pinnacle Boss Crash 2nd Stage

Hi, I found game bug related to crash Expeditional Pinnacle Boss (battle ended before second stage start). I think it is related to boss Frozen Sigil (doesn't get up when fight started, cause Sigil agro area small and work independent from expeditional boss).
