I’m having some doubts that your Irongut getting devoured made any difference here. The game doesn’t seem to keep track of specific troop related events of past turns.
Could you please post the team you have been using? Maybe there’s something else in there that might explain what happened. On a very wild guess, you have some source of Lycantrophy in your team, which hit the absolute jackpot of transforming your Valraven into a Valraven, voiding the sigils.
Is it also possible to check interaction with gnomes as well?
If Lycanthropy voids sigils from a raven, it’s highly likely that the same is true for gnome rewards.
Yup, Gnomes are affected, too. One of my guildies posted in guild chat that he did not receive any Gnome loot after the Gnome got transformed due to Lycanthropy.
