I set a move path on to a temple to bless. When I clicked the move button I got an out of sync error.
When the browser refreshed my unit was standing on the bless site but wasn't blessed. I had to move off and back on again. Not a huge deal except it cost me 4 extra moves (and 1 extra turn to complete the bless). I expect searching ruins suffers the same out of sync problem.
Also I believe that if you set a move path that crosses over a bless site/ruin that you don't get the effects as the units move over the site (Seen this once, going from memory).
