You are absolutely right! :)

Small screens or bad screens/projectors will make the numbers disappear (which would be nice since it seems like payday is much more expensive since the update).

It seems like I can't play level 4 either... (I can add that the part with level 3 has happened before).

Player.log

Not sure. I think I must have saved and loaded it to check if the issue persisted after the load.

There were no hidden Blade Lotus. The workers actually stand on it attempting to capture it but are disturbed and can't capture it for some reason even though there is no enemy nearby.

Could you explain this a bit more in depth?

Interesting! You should change the campaign to include this in some way to teach the player this feature.

Yes. Opening links in other applications open Firefox which is the default. Why not use the Steam browser?
