When I transformed a twilight Slaver Red into a twilight Nightshade Purple my abomination charges dropped to 0 permanently for my blue twilight Abomination. I could click it and the summon circle icon for the abomination would pop up like I had a charge ready but clicking to summon just did nothing. Was on Passage to darkness advanced. Can't seem to reproduce it when i tried on encounters with twilight though. Don't have time to do another passage so not sure if it's map specific.
