We do monitor User Voice; we share your disappointment that we don’t have a reproducible case, for this issue.
If you can reliably reproduce the ‘low level exception’ problem, on your system, please contact Support and provide them with any files and source media required for that repro case, as well as (important!) step-by-step instructions on how you can reproduce the issue.
We’re eager to pursue the issue further.

You are correct, all of the parameters reset when Duplicating a sequence. This is very troublesome. A work around (rather than duplicating) is to create a new sequence, and then copy and paste all of the contents from the other sequence into the new one. Parameters seems to come along correctly with the copy.
