frankdressel/mrdata — Issue #9: Merge is not working on data not directly taken from the dataprovider

State: open

When data is taken from the dataprovider (for example with Forest_time), each data element has a reference to the original element it was a child of. Nevertheless, this information is NOT preserved in most of the operations like addition, conversion of datatypes, ...

For using the merge command, the information of the origin element is essential. Thus, you cannot use merge on elements after you applied some operators on them.

Workaround: Merge as early as possible.
