RFA and BTA touching, is there a loser?

[1112-425XL]

I have 5 RFAs and one BTA. One of the rfas can't seem to find its happy place (the rest haven't moved in 6 mos.) and is constantly on the move. Recently it moved close enough to touch the bta. Is this an issue for one of them?

The RFA will move if it’s getting stung
