I swear I tried this and it did not even remotely work, or even come close to working, haha. I'm not sure what I'm even doing wrong. I added 340 to every line you highlighted, and yet every element (bar, hotspot bar, arrow) are just nowhere near each other still. I'm sorry!
I haven't tried it in a new project, only my own and also in the Cookie Cutter project and it works in neither. I'm doing a new project now, but now the arrow just flat out does not move, even before I change anything. I followed every instruction on the store page, and everything is intended, except the arrow, no matter what difficulty, just does not move.
Here's what everything looks like:
I added +340 to each of the highlighted lines, even the highlighted lines that were for the Y position and your original comment was to only change the X position, which is... confusing to say the least.
