Ah no! Hmm, so ok: can you go to the game's save folder (see the FAQ) and send both .log files to bighandinsky@gmail.com? (Title "Tutorial bug" please)
After that, try playing it again, but take it super slow - don't move the node tree at all until the relevant panel shows (I think the bug is due to a very specific timing when moving the map. I thought I managed to address it in a patch, but sounds like I didn't 😬)
