Continuity mistake: Rex has a bandage on his left arm for the entirety of the episode after getting injured in the previous one. After Aayla destroys the probe droid, in a shot of her, Ahsoka, Rex and Bly walking over to the destroyed droid, the bandage is missing. (00:07:11)
Continuity mistake: After landing the Separatist shuttle at the Lurmen village, Anakin, Ahsoka and Aayla get out and walk around the shuttle, underneath its legs, toward Tee Watt Kaa and Wag Too, as Aayla announces that the Separatists will arrive in moments. When she's finished speaking, the three Jedi have emerged from underneath the ship. The scene cuts to Tee Watt Kaa demanding to know why they came back, and when the scene cuts back to a close-up of the three Jedi, they're walking out from underneath the shuttle again. (00:14:40)
Continuity mistake: Rex climbs onto a barrier of pods that the Jedi built in front of the village to take a look at the approaching droid forces and reports that they have eight minutes tops before the Separatists' arrival, prompting Anakin to order the shield generators put in place. Cut to General Lok Durd and his chief battle droid, who look through binoculars at the distant village, where the barrier is shown as incomplete, with Ahsoka and Aayla still moving pods into place.

Answer: I guess that 1) the King assumed that Ventress' droids were meant to capture the Jedi, not kill him outright. When she yells at OOM-224 to shoot Yoda, she evidently failed that expectation. 2) Sending out a bunch of Droidekas after it is plain that Master Yoda has clearly won is not a sign of good sportsmanship, either.
