Hey, first of all, thanks for making Kinopio! It’s one of my favorite little tools on the internet. I love the vibe
I’ve noticed that in large spaces with lots of cards, sometimes cards or connections will turn invisible, and connections will go to weird places where they don’t belong. I feel like this only started very recently, maybe today or yesterday, but I’m not sure about this.
I had a hard time reproducing it, but after messing around for a while, I managed to end up with a board in this state: Kinopio – Thinking Canvas. (Note that the board is quite large.) Even when I open it in a private browser (tested Safari and Firefox on macOS), it has issues, so I think it’s not purely a client-side problem. Moving a card fixes all the connections related to that card, but sometime later (not sure what triggers it), the problem will reappear.
Here’s a couple of screenshots of what it looks like for me (first one is self-explanatory, in the second one, there’s supposed to be connections between many items):
