We're aware of a bug in Chapter 6. To avoid it, don't put the block on the mine cart!
If a block gets stuck somewhere it's not supposed to, try the Save History feature as soon as possible.
We're working on fixes as fast as we can and we'll let you know when they're ready!
Not every story goes as planned. If you are experiencing bugs, issues or just want to drop us some helpful feedback, we are here to help! DMs are open.
