I have encountered redstone issues where the specific location of the redstone circuit will effect how it works. This is most visible when using command blocks that change the area they are near, as the exact execution order can have clear effect. For instance, if you have 3 command blocks in a row, and they are all powered simultanously with a redstone signal, sometimes they will execute in sequence, and sometimes they will execute out of sequence. This seems to be deterministic based on where it is built.

I have attached a world where this behavior can be seen. You are standing on a platform with a level. When the lever is toggled, the platform will move one block forward, resulting in an identical copy of the current configuration in a different location, as well as teleporting the player forward. . You start with the lever at -10, 118 -111, and until it gets to -5 118 -111 it works, but when the lever is pulled at that location, the copy messes up
