I see. If you compile with v5.2.1 first, then it puts files immediately in "compiled", and those will be found by v6.1.
If you compile v6.1 first, then the files go in a subdirectory of "compiled", and they won't interfere with v5.2.1, while v6.1 will continue to find the files in the subdirectory. That's what I tried, so I didn't think of the problem with the other order. Were you able to solve this by compiling with v6.1 first? Or some other approach?
