So I got this card called "solo" and now I'm soft-locked at this screen that asks for me to play a melody (but no selection appears - only the gray overlay that indicates I can't take any other actions than selection).

It's among the characters I'm trying out so I don't know much about that mod myself, but there's no UI for Bard music so I assume Snecko can't take advantage of any of the bard's cards

It's probably best to blacklist them

edit: nooo I tried out a card from that Spell Scriber mod as well, one which takes two random spell effects from the deck. There was none and it crashed. Either that mod is broken when no spell effects are in deck, or this mod is incompatible with mods that add new mechanics. RIP Snecko is probably my 2nd favourite character to play so the fact I can't have as much fun installing random mods to make Snecko even more random makes me sad
