Hello,

With the following

theory Unused imports Main begin

lemma mylem: assumes "A ∧ B" shows B using assms by auto

unused_thms

I get this exception in Isabelle 2020 RC1 but not in 2019.

CONTEXT
("No content for theory certificate Draft.Unused:79", [], [],
["??.HOL.Trueprop (??.HOL.conj ?A ?B) ⟹ ??.HOL.Trueprop ?B"],
NONE) raised (line 528 of "thm.ML")

Cheers

Mark
