While playing using my touchpad on my laptop (who doesn't want a challenge when getting invaded by bugs), sometimes the clicks with the touchpad left-mouse button dont get registered in-game. I initially thought to be a hardware problem but I have tested the touchpad on other games and applications ...

Wow I have this issue and I've spent over 2 hours in this mission

Sad to see that the save files are unrecoverable but happy that no one will suffer through this. Thanks for the fix
