During the Trial of the Immaculates it is possible to inadvertently break the game by lockpicking the door to the left of the first statue (before you get Tenebrium poisoning) and approaching the Star Stone to trigger its reaction to the protagonists. If you talk to Loic at this point, he will still use his Silverglen dialogue tree for some unexplicable reason.
If you proceed to do the trials now, you will get Tenebrium poisoning, but since you've already used the Star Stone, you have no way of curing it. Talking to Loic now will have him use a new dialogue tree in which he is surprised that you are not poisoned and then he goes away. However, you ARE poisoned with no way of curing it.
Please consider making the left door in the first chamber unlockpickable or change Loic's dialogue tree to the post-trials one.
Just to confirm this is not working as intended and dampens the immersion.
I'd broken into here to cure a character of rot earlier (he'd picked up that control rod thing from Hiberheim), left, and come back later to complete the trial.
Everything was out of whack, like Poganin describes. Loic and the chicken went on about how I wasn't infected as my health cheerily dropped in the background and little purple numbers popped up everywhere. Plus I was glowing. Clearly a bug and while I suspect I'll be able to heal myself later on it's the immersion that took a dive here.
Please make that first door not lockpickable!
