Maybe you do not consider this to be a bug. However, I am using KNIME with Subversion and adding my projects, I usually get a bunch of errors because the settings files have inconsistent line ending style. It is very time-consuming to fix this.
I have been working on Windows only with KNIME the last weeks, wo I cannot tell anything about cross-os issue. However, I had this problem with stuff downloaded for your courses. I am currently working on L3-CD.
I presume, you should find this behaviour when you drag and drop course exercises, I discovered it at L1-DS and L2-DS is affected too, into KNIME on Windows (10). You also can have a look at the attached screen capture. [redacted]
I did not do any research on which line break was prevailing, but I feel there are more windows style line breaks within.
