I've fixed several important issues with Beta 6. Let me know if it works for you!

Improvements

• Improved the mission generation system to always have the same amount of enemies per mission
• Show the top storey when no agent is selected and no agent has been deployed
• Reduced the intensity of the ambiant occlusion post effect
• Updated translations

Fixes

• Fixed the memory leak causing crashes while playing on multi-storey maps
• Fixed character selection getting cancelled during the execution phase
• Fixed door kicking stunning enemies on the same side of the door as the opener
• Fixed the default "toggle wall hiding" shortcut
• Fixed the presence of character spawns linked to upper storey windows in some generated maps

NB: this patch has also been applied to the demo and the prologue versions ;)
