Years 1-4

 * 1) When you find all 200 gold bricks it will  unlock a bonus stage in which you get to play Voldemort, who's objective it is to rampage through 1981 London to accumulate a certain amount of studs.

Years 5-7

 * 1) After completing all the story levels. The level takes place in a small Lego town (consisting of various Lego Harry Potter sets released between 2010-2011). Your objective is to wreak havoc in said town which gives you studs. Reaching 1000000 studs completes the level.

Overall

 * 1) The PC version of both Years 1-4 and 5-7 are prone to crashing and freezing at certain points in the game, making it impossible to progress further.
 * 2) You can't play with a mouse on the PC version.

Years 1-4

 * 1) The Forbidden Forest levels. Not particularly hard levels, but there are a lot of lego flowers and bushes lying around and if you want those LEGO studs for True Wizard (not to mention buying unlockables), you need to spend a good amount of time destroying all of them. Fortunately, the Multiplier red bricks makes this a lot easier.
 * 2) Voldemort is ridiculously easy for the final boss. His entire boss fight consists of defeating a few Death Eaters and the occasional Beam-O-War between Voldemort and Harry, where you need to button-mash your way to victory.

Years 5-7

 * 1) The Wii version of 5-7 is almost just as the PC version, as it also freezes incredibly constantly. The worst part is a glitch with Aquamenti, where if you shoot it at any fire that you can't put out, the game automatically freezes. This makes certain levels ("A Not So Merry Christmas", especially) near impossible to complete without being very careful. As the Wii couldn't receive game updates like the other consoles, a later pressing of the game fixed this issue.
 * 2) The Vita version of Years 5-7 can have the framerate drop to abysmal levels; why this happens is unknown, since the original PSP version runs just fine.
 * 3) The Slytherin Crest in the "Magic Is Might" level. Not only is it hidden behind a pillar, but you are being chased by Dementors so you have very little time to detour for it. Plus, if you miss it or get caught by the Dementors, it respawns you after the Crest, so you have to play through the entire level and redo the very long boss fight for another shot at it.
