No convergence is reached for the equilibrium structure of the vexing fulminic acid molecule as the DFT ladder is climbed. Rather than providing clarity, the 473 DFAs employed here only produce chaos. Qualitatively, DFAs in Groups 1 and 2 overwhelmingly produce incorrect bent minima. This deficiency is incrementally rectified by Groups 3, 4 and 5 until no bent minima remain, but the DFT ladder ultimately topples at Group 6 with a relapse back to a majority of bent minima. Analysis of ΔEe(rxn) provides another vivid collapse of the DFT ladder.
