I think you mean The Castle level with the light house with treasure ontop?
Yeah in that level I was mr evil and put the key under the treasure ^^;
and I knew about the spawning glitch its really bad luck if you get it, so I put a death floor under the level but I fear it did not work for you there.
Yes I do have a squashing themed discord so if you wanna join I will put a linky here:
