I added some translation to those objects in Base texts which are missing S. Chinese texts, but some of them have been removed.
Those objects are: Don't build bridges, automatic terraforming, Don't build tunnels, Please select a way to build!, show_construction_info, Stack toolbars, Way builder.
I noticed those objects have german translation, so I finished adding the translated texts of them. I'm not sure how they were been removed.
The translator is very slow for me today. Maybe DoD gremlins are around. ;) But I just updated the translation text less than a day ago. I had to upload them twice, since I forgot some strings. Maybe in that short interval, I accidentally overwrote your very fresh translations? (But I thought that reupload of the same string should keep the translations.)
