Having played through everything about one-and-a-half times and gotten up to ninth level spells, I think I'm done with Icewind Dale on the Nintendo Switch for now. I've been taking videos and screenshots and compiling information to be able to share the bugs I encountered here. For better video quality, I recommend clicking through to Twitter and watching it directly there, not sure if that's something others experience or if it's only true for me.
This first set of bugs were described in this thread.
Essentially, every contingency and sequencer is broken.
This XP bug was mentioned in this thread.
This spell-sharing bug was one I explored in this thread.
The rest of these I have not seen mentioned anywhere else.
This next bug is quite severe and I constantly struggled with it throughout the game.
Finally some very minor display bugs and issues.
