A series of publications of the WASA Collaboration culminates in a recent paper of Pricking, Bashkanov and Clement (arXiv:1310.5532) claiming a ΔΔ dibaryon resonance at 2370 MeV. However, as explained here, there are logical flaws in this result. A natural alternative arises from the reaction pd → NN *(1440)p s , where ps is a spectator proton. There is supporting evidence from a recent experiment of Mielke et al. on dp → 3He π + π −.
