Welder Resource Drain Bug - Reproduceable
The bug causes the welder to use thousands more resources to build a hydrogen tank than the required amount. I am unsure if this affects other blocks, but it can be reliably reproduced using a large ship welder and hydrogen tank.
The welder drains resources in two bursts from the cargo container. The first burst is thousands of resources being used (and thus deleted) and a second burst subtracting the actual required amount of parts. This can be seen by watching the cargo container inventory while the welder is on. Grinding the tank down will only salvage the exact amount required to build it. This bug does not occur with Engineer tools.
Provided are a world in which the bug can be reproduced and tested and a video of the bugs reproduction in a vanilla offline world.
