I find these glitches happen only when I reload Freeplay from a save. The first one, which I am sure is fixed, is that the pathfinding is destroyed temporarily when I reload. Again, I am pretty sure its fixed, but not 100% sure. The second one is the most frustrating for me and does happen a lot. When I reload, I cannot harvest creatures near my nest permanently. The ants seem to try and harvest them, but stop. The job then is given to another to repeat the process.
