I posted this on the CurseForge issue tracker but I figured I'd also post it here.
In adventure mode, you can't light unlit candles, campfires, etc with flint and steel. However, if you give the flint and steel the correct "CanPlaceOn" tags, you can. However, for the supplementaries Copper Lantern and Candle Holders, it instead places fire on the block next to the right-clicked face as if the lantern/candle was a full block, instead of lighting the lantern/candle, and leaving it unlit.
I know its a weird niche issue, but I'm very surprised that this behavior isn't just automatically worked in by the game.
I'm using fabric 1.19.2 and the most updated version of supplementaries (2.3.11). Since this is not a crash I don't think the log really helps here.
