Just a few graphical glitches I found so far. Fresh install of 0.85 on Win7 64-bit, nVidia GeForce 610M, driver version 8.17.12.8548.
1. Missing 3d models on sov selection screen.

2. String placeholders in the "merchant" trait. Also, this trait was not listed during sov selection above.

3. Sand golem health bar filled with random noise (varies from battle to battle).

4. Trait tooltip [A] on the tactical unit infocard is glitchy; it appears briefly and disappear immediately. I noticed that after it disappears, there is an extra unit tooltip in the top right corner [B], maybe that has something to do with it. Also, sometimes the unit tooltip doesn't show up at all when hovering over a unit on the tactical map.

Nice work otherwise! Cheers.
