here are a couple of small bugs with (anti-Leaden-Key) Aloth's approval system:
1. Talking to Rabyuna with Aloth and Tekehu in the party, Aloth disapproves of a Tekehu's prideful response, but the Watcher gets negative approval.
2. Asking Tekehu "What do you hope to gain by finding Ngati's covenant on Ukaizo?" has him give a pro-autonomy response, so Aloth approves... every time. It's not just cosmetic, it actually raises the total score.
3. Also, there's no quotes for any of his reactions to Autonomy.
Here's a save game file from The Wild Mare where these conversations haven't been initiated yet, so you can reproduce the bugs easily. Dxdiag and output log are attached below.
