Not sure whether this has already been reported or not but a quick look around the bug section didn't reveal any similar reports so here goes. I managed to break salvaging
Here's how, I;
-entered a debris field,
-miss clicked on a empty slot in my hot bar,
-managed to correctly hit clicked Salvage
and that's where things went bonkers. Clicking the empty slot paused the game, hitting Salvage unpaused it, while also causing the salvage dialogue to pop up. I now was in a dialogue while the game was still running in the background. Sadly I couldn't move my fleet around, though I did see the messages "breaking orbit" and "entering orbit" pop up so something was nonetheless happening.
For some reason I was also able to pound the field of scrap into more scrap, although my men didn't seem to understand my orders as pressing "give the order to fire" didn't actually do anything. Can't really blame them to be honest
Proceeding with normal scavenging procedures only made it worse, as no matter how many times I salvaged the same field (following the same steps), I kept getting exactly the same amount of salvage (metals, supplies, fuel etc.)
I originally encountered this on a modded build, tested and verified (for myself) that it also happens on a unmodded build. I started a new save with tutorial, followed the same steps and boom, holds were full
Don't really know what's going on here, but it sure isn't kosher as one could easily load up their holds with supplies and fuel from just one debris field, never needing to make port again.
