Several problems

I'm currently experiencing several issues:
* I can no longer activate the bosses that drop essences. I was able to start the first two, but after failing the 3rd group, I can no longer activate or interact with them. Nothing happens.
* I failed the 2nd trial of Sekhama. I received a failure message, but immediately after, I saw my life energy increase, but I couldn't return to the starting point. The game seemed frozen. I had to force-quit PoE and restart it. All relics and Balbala's coin were gone.
* I frequently lose connection when trying to teleport back to the hideout. This error occurs mostly in the evenings and often multiple times in a row. This significantly impacts the playability of the game.
