2.0.13 dragging belt over a blueprint with undergrounds places only the first underground

[whimzero]

Easy to replicate.
1. Place a belt down, horizontal for example.
2. Ghost-drag belt across it so that it auto-forms undergrounds.
3. Then, actually drag the real belt over the ghost belt+underground. Only the first underground will be placed, the second will remain a ghost.

DIdn't find it on first search, but seems to be same as: viewtopic.php?f=7&t=118421&p=628525&hil ... nd#p628525

I think it is different just because yours is the ghost underground building and it's only building the first with the second un-built. I was just about to post about yours but found in the search. Also happens in the other directions, regardless of belt direction (up, down, left, right) the first underground is built in the blueprint and the second stays a ghost.

Thanks for the report, this is a duplicate of 117222.

This predates 2.0, earliest I could find: 94307.

I have the same problem. This problem only started with a patch earlier this week and does not look related to the linked tickets. This is specifically about dragging, which was working fine before.

Actually, it is neither of these. It did not happen during 1.x because i used similar blueprints without issue - they worked as expected. 117222 seems to be about using different underground types, but this was yellow belt over a yellow bp. It more closely relates to the item i listed in my link though that doesn't deal with blueprints - it is caused by belt dragging (and auto undergrounding) across 2 or more perpendicular belt undergrounds. Same effect as was shown here but that can be done without belt ghost present. Definitely a bug in the belt-drag/underground logic.

It is actually just 118408.

[whimzero]

agreed. that is the same.
