Right after I get a blood bible, the game usually gets stuck. My character would be unable to move, talk or even log out. I have to force quit the game and log back in to go back to normal.
Follow up:errr well it was like that at first now it happens with the storage npc in Army guild 1 and Tanya in Training Grounds >.> It's a pain because I have to go back to get bibles afterwards

What level was your character at the time?

Was around lvl 49 when this happened. It would say I had equipped the bible and then not allow me to move, talk or even log out after that.

Did you try dropping the bible?

I don't believe a level 49 can participate with the bibles, and you likely walked there or however you got there.. I think that might have been the issue, not being over 100+
