Example document showing the bug.

Please follow this algorithm to reproduce.

Please open attached file in Draw.
See the attached image (#1) where I've highlighted a connector that is draw in a rectangular shape.
Highlight it and disconnect the (bottom) end with the arrow head.
Reconnect the connector to the point where it was disconnected from.
The connector is now drawn as a arrow-headed line pointing downwards.
Save the file.
Close the file.
Re-open the file.
The connector is now drawn as a rectangle and look like image (#1) again.

The bug is present in both Still ( and Fresh ( I haven't checked any earlier versions.

I seem to remember some similar bugs..

Found a similar effect with the standard connector (skew = 0, spacings = 0 ... 0.5 cm) in LO under Linux x86-64. My connector establishes a right angled connection between two objects. After save and re-load a rectangular loop is created within the connector. The connection can be corrected by clicking on one of the segment handles and move them a bit.

One gets the feeling, as if the routing information is not completely saved together with the rest of the connector information.

Interestingly, I have found incorrect connectors only in re-opened odg files but not in re-opened fodg files. Please see the two examples attached. The odg example includes screenshots of the pre-save and post-open appearance.

Confirming the issue (Example file with bug > reconnect objects > save > reopen = misaligned connector)

Still present on Windows

This works fine for me on Mac master. On 6.0.2 mac release it briefly shows up wrong and then renders correctly after one second. On 6.0.2 windows it still renders wrong

May be worth if someone can check on Windows master
