Umbral Gem glitch in Act 2 workaround

[[YORHA] B-1"SMARCK"]

During Act 2, when you follow the quest for the Nightsong, sometimes the game glitches out when using the Umbral Gems MOSTLY due to mods (if you happen to use some). The easiest workaround is to use the KNOCK spell on the door which will open it. Check your inventory for a scroll or respec a character with Withers.
It can be used to skip the temple quest but I STRONGLY advise to stick to a "normal" playtrough and use this IF you find yourself stuck.
Stay excellent out there (especially Shadowheart believers)
