Error while running event ctg::on_chunk_generated (ID 12) ctg/lib/randgrid.lua:20: attempt to index upvalue 'data' (a nil value)
It happens after aprox 10 sec
Thank you for letting me know, I have fixed this bug in 0.2.1. The bug was that I had forgotten to make the Maze3 pattern save its data when the game is saved.
