Let Y\mathord/\mkern-6mu/θG be a complete intersection in a GIT quotient X\mathord/\mkern-6mu/θG cut out by a G-representation E. We show that the E-twisted quasimap I-function recovers invariants of (Y, G, θ) if its nonequivariant limit exists before restriction to Y\mathord/\mkern-6mu/θG. This corrects a conjecture credited to Coates-Corti-Iritani-Tseng. We explain how to correct computations in the literature based on the faulty conjecture.
