Tried the sandbox this morning and again hour or so ago. The sandbox and pathfinding works very well, the villagers do reliably get to their destination (and in one case, switch paths to a better one). I did notice three things in my playthroughs though. Firstly, the game crashed during every playthrough, though at different times. The only common factor I know of is that I was building things. More trivially, removing the delay on the delete tool made it function like a raycaster, deleting everything in the players line-of-sight. In addition, the larger villagers now do not fit through doors. A 1×3/2×3 door would be sufficient, or possibly returning the hitbox to the old size.
I fixed a game crash but I'm not sure it was the one affecting you, please test and if it crashes send the log file. I am slowly tackling some of your suggestions whilst also adding other stuff that I feel like. You are welcome to bring an issue or a suggestion to the surface again if you think it is important and I should get to it sooner. Thanks again for your advice and feedback! Also if you take any screenshots or video clips I can use them to freshen up the main page.
