Hello, nice to see a mapper who wants so sort out problems! Just fwy theese issues you really have to be unlucky, but i still managed :D

The best way to show is with pictures, so i made a quick document in docs

Hope this helps

Yes, this helps tremendously, thank you so much for taking the time and effort to report these problems, with pictures no less! I changed the airvent so hopefully you won't be able to get stuck there anymore.

Unfortunately, I haven't been able to recreate the other problems you mentioned. All the floor is considered out of bounds, so I have no idea why the ball won't reset, and, have no idea how to fix such a problem short of replacing those out of bounds tiles with other out of bounds tiles. Hopefully the reaaaaaaaaaally unlucky part holds true so it doesn't become a big issue, but if others keep getting stuck in those spots consistently, I will definitely redesign those sections to use a different floor that will hopefully cause the ball to be marked out of bounds and reset accordingly. I'll keep trying to break it though and see if there is anything I can do about it. Thank you so much again, and if any other problems crop up, let me know!

My only problem that I had was hole 12(?) (the dice tower), 5 times in a row I plopped down on the collector disk and fell through the hole into the tower as intended, but I gained so much horizontal speed that I got shot out the side when I reached the bottom of the tower.

I have no issue with some randomness in my gameplay, but an 83% failure rate (from my experience) is a bit much.

Overall I really enjoyed the course! Keep up the great work.

OOF yeah, that was definitely not my intention when designing that hole, and in my testing it only failed once but I should have changed it then and there when it was even possible to fall out. Sorry about that, it should be fixed now. Thank you for bringing this to my attention!

tons of invisible walls and glitches. hole 9 is a lie. hit the invisible walls on the opening shot 4 times. bounced off water and went into the hole and it didnt count. someone i was playing with hit the same shot and it counted. this course is trash.

Unfortunately, because of how water is handled in the Course Creator, a ball will go OB unless it pretty much lands in the hole very shortly after leaving the water, IE, you have to be pretty perfect to get a hole in one on that hole. There is nothing I can do about that, and I don't really feel like re-doing that particular hole to not have the water, so that will stay. Either take the safer route, or go for glory.

The other stuff on that hole I might look into, because yeah, that one is pretty wonky, but labeling the whole course "trash" because of one bad experience on one singular hole seems a bit harsh, but whatever.
