Beaming with pleasure

Thank you so much for the improved beaming functionality!
It finally works as it should, and asking critical questions about it shouldn't be necessary — nevertheless:
I was working on a 9/8 file (bolero-type rhythms) when the update became available. While working in build 258, the rhythms (see picture 1) were actually beamed as the should be according to the meter. When I opened the same file in build 261, all the correct beams were broken (picture 2) and I had to manually re-beam the entire file.
Is the improved beaming function really set up to change beams in a completed file without telling the user?!
Best,
Thorrild
