Thanks for the praise! And thank you for enjoying the Linux version!
I'm aware of most cases where units get stuck, this was my first time writing an A* routine so there was so much for me to learn hehe. Most of the pathfinding issues only show up for the player because the CPU will keep telling units to attack the player, so it was hard to pin everything down. The bug with the units going missing I wasn't able to reproduce, that's new to me. However there is a bug where if you place a production facility's exit on the bottom of the map, or against a terrain blocker, the produced unit will be out of bounds or stuck.
