I've run into a few bugs with the 2.1.2b install (installer, all options except Cassidy TH and smoking anim). If you talk to father Tulley about the Abbey wine and come back with the bottle, there is no text available to give it to him. But if you talk to him about the abbey for the first time with the bottle, then you can complete the quest.
The science hologram in EPA doesn't seem to be registering my character killing things with the scorcher, so I can't finish the quest to test it. Also, my character has the quest to repair the voice computer (??) in EPA but I never actually _got_ the quest, so I have no idea what this is. There is a 'useable' vent on a level that doesn't nothing / goes nowhere, and the doors that require passcodes seem to be a little buggy. Even when I don't try to guess the passcode, next time I use them my only option is 'exit'. All posted to wiki, and have save games.
Kinda OT but what am I missing about repairing the EPA light generator on the 2nd level of the EPA? With 114 repair, it just get the message that "something is wrong" with it.
