Hey ZdenekDrizga, thanks for reaching out and apologies about the delayed response from our team.
I've had a closer look, however it does not appear that this issue has been brought up before, therefore for reproduction purposes, would I be able to ask for the following:
1. Video footage or screenshot showing the issue. You can then upload it to either video or image sharing website and send us over the link so we could take a look at it
2. Save file of your game in which you ran into this problem. It is normally by default located in %userprofile%\Documents\Anno 1800\accounts.
Once located, you can just simply upload it to any file sharing website and send the link over to us so that we could take a look at it.
Alternatively, you can submit a support ticket in our website by logging in and selecting 'Contact Customer Support. You'll need to compress your file before uploading.
Let us know and we will take it from there!
