Had Aegis Barrier VII. Went to upgrade it to Tytan. Hit the upgrade button and the unit info showed flickered but still showed Aegies, hit upgrade again and it worked fine. Play for a little while longer and notice I only have 2 of my 3 Vira Savior. Scrolls through TimeWarp but couldn't find one with all 3. Decided to mess around in formation editor and moved the last Tytan Barrier I upgraded. Had 2 of them sitting right on top of each other. Tried to delete the extra. It stayed but I was now down to 1 of my 3 Vira Savior. Couldn't delete the extra Tytan either. Was able to have enemy destroy it. But No idea what happened to the 2 Vira Savior.
Edit: Apologies, android Galaxy S8. everything fully up to date.
