Typically, there would be no interference between parts in a place that would cause this to occur, however; I’ve been having an issue where touched event is firing without touching a part when large parts are nearby. This is not place specific and only happens at certain areas of the map
Example:
Each part called origin is spawning a brick, bricks that spawn around the red spawner always explode (red part below explosions in picture), while green spawners parts don’t (correct behavior). Parts from the red spawner explode before touching another part because they believe they are touching the large green grass brick (not shown in picture)
Here’s a repro file of the above example
