Sorry for the current update frequency, but the Bloodlines community is quite un-dead at the moment
As for other major changes, the gum-not-giveable-bug of 5.1 has been fixed and the new guard already promised for 5.1 should now be at his place in the Empire hotel. I've added about a hundred new idle expression to about thirty NPCs and didn't test them all, so if anyone looks stupid now, please tell me. The same applies if you think some expressions should be emphasized, and for anyone interested a list of the states used is in the readme under restored stuff. Last not least I finally dared to meddle with the stealth rules and made the stealth quite a bit more realistic and harder that way! Again, I tested the tutorial and the Tawni quest which are still doable, but if you think the new rules are too hard, please give me feedback. Of course this change is plus patch only. The rest of the changes are listed below:
