could you rename the map keeping the map name as chapterinfo.upk makes it conflict with others that do the same really wish people wouldnt do that but they do

How do you get the sticker again? (its out of bounds)

Very neat little chapter, I love when people go beyond just importing stages and adding vault codes, and give it their own spin
Some issues I encountered though, if you die in the engine room the timepiece will not be spawned when the level reloads, you have to exit and grab the key again. The crows in this room also hit you before you are able to move at respawn due to their speed settings!
The ladders against walls can also push you inside the wall and softlock you when holding forward at the top. best solution without having to adjust the ladders again would be a trigger volume that teleports the player out of the wall!

is this the one with the toxic water?

YES! WE'RE BANJO KAZOOIE LOVERS >v<
