As discussed, I updated the Proximity behavior. There are now additional options to select all objects within the proximity, or just the first one found.
As requested, I fixed the issue where the proximity triggers on itself. I didn't make it an option, since it didn't seem like reasonable behavior - I just removed it.
I also fixed an issue with attachments not re-attaching after removal
There was also an emitter update - when emitting an object with rotate to match emitter *disabled* and independent angles *enabled* the object is rotated to point in the direction it is emitted at. This seems like a more reasonable setting for this case, but let me know if it breaks anything and I'll try to address.
Let me know if you find any issues with this update.
