I can't find the save where that happened and haven't reproduced it yet, but I have one where clicking the policy button doesn't bring up the policy page-- This is with the "policy saving" option on. It should still bring up on left click though, and it's not. Minor issue compared to other one. I'm using 1.29b7

I'll get a save if I get the other, bigger policy problem again.
I also had a crash at turn 34, but loading save from turn 30 and doing the exact same chain of actions did not reproduce it... I wondered if it might have been related to me dragging the map around while other turns were processing, but again I couldn't reproduce even with that. Very frustrating, but I actually have not had many crashes with this version so far.
On non-bug related notes, I really like the movement previewer thing. Though with my mild colorblindness, the blue color is sometimes hard to tell from a river

I love the feature though. On the movement preview, would it be possible to also add a "move to" target of where it's going to end up on a multi-turn move? There are mods for this, it just seems like it would fit in here.
Also, the big icon on the barbarian encampment is pretty hard to distinguish from the barb camp itself -- the barb icon is handy though, when a CS has a mission about barb encampment, and it zooms you there, but then you can't find it again, such as in fog of war. Also not sure of the plans for the big icons you have -- it doesn't go bonus resources, but if I turn of the vanilla resource icons and leave just your big ones, then there's no icon on bonus resources. It looks like you're going for an icon presentation kind of like is on the strategic view, but on the normal view, which is neat-- maybe have an option to highlight or have like an X icon or something on unimproved resources?
edit: also, I don't remember the right ribbon for players highlighting the current player's turn.. maybe I'm just blind. It's neat though
edit again: for the big icons, could you include natural wonder icons? In vanilla, it only shows their icon the first turn they're discovered. I'd like to know where they are permanently
