[Bug 1.49] Resource line displayed wrong

When placing resource-lines (in paused mode), sometimes the line is not connected at all.
The ‘beams’/transpart-lines are all looking in different direction.
Only after un-pausing the game the line is fixed and shown as connected again.

Hi, is this just a visual thing? with regards to the graphics falling into place? do you have a video that shows it?
Cheers
