Lead Level Designer
This was actually a bug, will be fixed in the upcoming update.
Thanks for reporting!
The lighting randomly changing by hitting escape has nothing to do with the lighting itself. It's an issue in the exposure system, which should hopefully be fixed in the next update.
Foliage shadows in water is an issue with baked lighting, will be addressed in one of the upcoming updates.
The area under the large tower and the "poorly" thought out security base are missing assets. Will be fixed in the next update.
Keep in mind this is a beta and things can break during these final weeks.
Do you have this issue on all current beta maps?
Could you maybe provide a bit more info or more zoomed out screenshot of where this location is? It's a bit hard to find right now. Thank you!
