Most of these bugs are minor, but I'd thought I'd report them anyway. Aside from these bugs, I am enjoying TM2 Stadium very much--the copy-paste function in the editor makes creating large buildings so much easier, and I love the Formula One-esque engine sounds! I look forward to the full version with more tracks and blocks, and I've already plunked down $8.99 for it. Thanks, Nadeo and Ubisoft!

Bug #1 [HUD]: (This bug was previously reported here. All other bugs in that thread seem to have been fixed.) After a race ends, the lap counter shows (n+1/n) laps, where n is the number of laps in the race. For example, in a 5-lap race, the counter will show 6/5 at the end of the race. Here's a picture.
How can I reproduce it? Complete any multi-lap race (in TM2 Canyon or Stadium).
What is my expectation of this bug? The lap counter should not exceed the number of laps in the race (i.e., it should end with 5/5, not 6/5).
Bug #2 [Editor, ManiaScript]: The Latest Blocks plugin no longer works properly--if I try to select a block from the list, a compile-time error comes up.
How can I reproduce it? Activate the Latest Blocks plugin.
What is my expectation of this bug? I should be able to select a block from that list and use it, right? I'm pretty sure that's how it worked in TM2 before, but it seems an update may have changed the names of some variables, rendering the script invalid.
Bug #3 [Graphics]: The starting lights in Solo A10 appear to flicker. To me, it looks like it might be caused by Z-fighting.
How can I reproduce it? Start (or restart) playing Solo A10 in Stadium.
What is my expectation of this bug? The starting lights should not appear to flicker.
Bug #4 [Art]: The Stadium car's tires are not uniformly covered with dirt after being in the dirt for a while. (See this image; there are dark bands on the tires delineating patches of dirt)
How can I reproduce it? Drive in dirt until it accumulates on the car.
What is my expectation of this bug? The Stadium car's tires should be uniformly covered with dirt, right?
Bug #5 [Art]: Some textures are very pixellated and glitchy-looking when viewed close-up, such as these on the left and right dirt chicanes (picture).
How can I reproduce it? Place the above-mentioned block in the editor and look at it close-up.
What is my expectation of this bug? Those textures could be smoother, and the old "United" "sub-texture" should not be visible.
Bug #6 [Art/Graphics]: When any sign such this one is viewed from far away and at certain angles, it looks pixellated.
How can I reproduce it? Place any sign in the editor (with any decoration) and look at it from an angle like the one in the picture.
What is my expectation of this bug? Any sign's appearance should be consistent from any angle.
