I can name more but I'll pace myself.
How did Kylo get to the salt planet ahead of Rey? She left him laying down while she escaped. She also has the fastest ship in the Galaxy. When she finally shows up, the battle is over!?!
And how did DJ tell the First Order the plan of the Resistance? When did he ever know the plan? Hell, Poe didn't even know the plan and he was on the goddam ship!!
