Small Projector not keeping blueprint in case of using a Large Welder.

Bug is in current version, 21.05.2019

I found the bug in single player while trying to quickly produce hand made missiles.

(I later realized realized that I was using an unlimited speed and thruster force offset mods, tho it's pretty likely they wouldn't affect the results.)

(I'll playtest again tomorrow with large grid projectors too, and report back again, hopefully with a video. I wasn't focusing on the bug today.)

In the following I talk about a case where I built in creative a small grid (in my case torpedoes) using Welder block(s) and a small projector on a Large grid (using rotor connection so everything is part of the same grid_group):

With my current knowledge, the bug occurs when a small grid Projector is projecting a blueprint and a large grid Welder builds it.

While finishing the weld, the Projector looses the blueprint and it has to be added to the Projector again from the library. Even if 'Keep Blueprint' is checked or not.

I also noticed, that blueprints made this way get a small starting nudge from a mysterious force from the grid somehow because their path becomes disturbed (even if the welder or other blocks are not close of course). In the other hand, small grid Welders do not remove the blueprint from the Projector and don't cause any nudges.

The problem always happened as of now. I don't know if this is intentional or I'm missing something. Feedback would be great especially when if I made a video.
