Well as the reload from a savegame is well known I am not testing that as it is not a bug, Civ battles played that way too- once the random result is calc'ed it saves with the savegame.

I did get a chance to see if it got stuck on my test game and was unable to replicate. Had a group of 7 noob spies with 93% chance to get into Paris (thing I hate most about this test is the spies train up and I lose my batches! Grr!) but the first guy failed, THEN the second guy failed as well! However third and subsequent spies all made it and with the odds of two spies @ 7% failure hitting twice in a row at basically a 1-in-200 chance this is going to happen sometimes. So once back in the Imperial chair later on tonight, it's back to testing........
