I made an end credits crawl with 5 different elements. Same fonts and font sizes in every element. 2 of the elements (1 and 4) have a blank line after each credit, just to make the names to seem more important. All the others have a credit on every line. Every time I reopen the composite shot to make some small change it all looks good but when I render it there all of a sudden are four blank lines between credits instead of one i elements 1 and 4. In the other elements there is one blank line inserted between every credit where there is supposed to be none. When I look at the composite shot again (without restarting) all looks good. The only way I get it to render properly is to rewrite the whole credit list once again. And that is not so fun. I have the latest update of HF 2017 (9 march). I have AVGA Geoforce GTX1070 and 64 GB Ram. The render is 1920x1080 mp4.
