Discontinuity, Plot Holes, Errors

 * Why did the Doctor act as if the TARDIS was useless without his key, when he has a spare key hidden in a secret compartment over the door? Maybe he removed the spare because he didn't want Klein to know about it or about the compartment. Or maybe he just wanted a chance to look for the original key before resorting to the spare. In any event, Klein allowed him no chance to get at the spare key.

Continuity

 * The removal of Klein from the timeline in The Architects of History probably resulted in the events of this story being either changed significantly or prevented entirely. The Doctor may have visited the Vrill homeworld alone or with another companion, but his/their adventure would certainly have ended quite differently.
