A good start. In the future when making a hot fix please update the name of the download to reflect that as it can be difficult to know if using the hotfix or not if the name doesn't change. v0.1a or v0.1.1 as example.
Saves still have issues, buildings seem to never get built when loading a save.
If you wish to restart the game you have to close and reopen the game otherwise there won't a worker to unfreeze in cryo when restarting to that point of the story.
Combat is excessively brutal for a start. It already takes 6 days to be able to do a mission, for it to have as high a chance of failing means a lot of save scumming or restarts. For lore could explain that because the slow upstart to the captain being unfrozen, most aliens forces near by are currently scouts with a much lower health pool.
Currently the miner feel too weak to be viable and so when using them just increases the chance the mission fails. Ideally there should be something akin to rock, paper, scissors. Enemies that are weak to miners, enemies that are equal to miners, enemies that have an advantage to miners.
Suggestion being Miners are a melee fighter because of the impact hammer, so strong against heavy armor tank type aliens, weak to ranged alien fighter, equal to scout type enemies.
Where as Marines could be strong to scout, equal to ranged and weak to heavy tank.
