Ok, I'm really upset now. I managed to reach the last room on the top of inside of pyramid without using shortcuts... and I can't open the chest and teleport to cloud! It's unfair.
Flippy, I didn't notice any suspicious things while proceeding to chest with bottle at the first time. As I said that was 1.12.1a and all shortcuts appeared properly after I passed certain sections (e.g. falling boulders area before snaking bridge). When I reached the chest I took several bottles, created several cloud-in-bottles, jumped to top right platform and entered the shortcut. I walked through dark tunnel to the left shortcut and appeared in the beginning of the level. Beams under the shortcuts weren't activated. I checked video walkthrough and understood that something goes wrong...

I'll look into why you were able to grab several bottles from the chest, that right there seems to be where things went wrong in the quest logic.
