Wrong feature locations after sticky-end ligation

[jan-glx]

The new feature locations computed when adding two DSeqrecords with sticky ends are off:

from pydna.genbank import Genbank
from Bio.Restriction import BamHI, NdeI

gb = Genbank("[email protected]")
puc19 = gb.nucleotide("M77789.2")
bb, insert = puc19.cut(NdeI,BamHI)

puc19_ = (bb + insert).looped().synced(puc19)

print(puc19_.extract_feature(2), "\n")
print(puc19.extract_feature(6))

Thanks! Ill have a look at this.

[BjornFJohansson]

Still working on this, regular work came in the way.

[BjornFJohansson]

Have a solution for this, look out for a new release.

Solved in 5.2.0 I hope. Feel free to reopen if not.
