1. Once you find the key to Gharik's Lab, don't leave it without setting a Lloyd's Beacon some place beyond the door. If you leave without setting the Beacon, when you come back, the door will be locked against you. If the bug bites and you end up with a locked door, save your game and edit the savegame to give yourself another key – Elrond's Editor works very nicely.2. There is a recovery bug with the armour. My normal parties don't have any members that wear plate armour. What I usually do is, when one of my characters reaches master in chain, I use the editor to give him/her master in plate, which gives the character the recovery benefit in chain. Similarly, master in chain gives the recovery benefit in leather, and I think the master in leather gives the recovery benefit in shield. I don't know of any way to give characters who wear plate the recovery benefit.
3. According to Bones' combat guide, you actually do more damage using one weapon rather than two. But I prefer to use two weapons, and I'm happy to play the game that way.
I've been playing the v1.0 game since it first came out, and I'm perfectly content to play it that way. If you have any further problems, get back to me, and I'll help to the best of my ability.
Enjoy the game!
