The film although based in the year 1893 shows quite a few British Lieutenants to be clean-shaven. The British Indian Army regulated all commissioned officers to wear whiskers till 1910, so the lieutenants had to wear beards or at least moustaches.
SPOILER. Every time British soldiers go past on horseback, the Union flag carried by one of them is always upside down. As an internationally recognized distress signal, it's an unconscious revealing of the result of the cricket match.
When the cricket match scene is being shot, and Ismail got out as Tipu was run-out by the bowler, there is actual an omission of 1 ball. In a game of cricket, which is driven till last ball, calculation of 1 ball less is a major plot hole.
