When you return to town your followers that aren't accompanying you have the wrong gear displayed. Ex: The enchantress is accompanying me, and when I return to town the templar has a spear equiped (like when he first takes his equipment out of the chest when you rescue him in the cathedral). Only after opening his inventory do the right items appear (spear and shield in my case).

Repro steps:

1. Load a game.

*Note: If you look at your followers at this point, they will have the right equipment selected.

2. Leave town (I left act 2 by way point).
3. Run around a bit, kill a few monsters, open some chests, etc.
4. Return to town.

*Note: If you look at your followers at this point, your followers not currently accompanying you have the wrong gear displayed. You have to open their inventory to see the right gear.
