Here is the situation : I was installing (downloading) MadMax (32GB) through Galaxy, and a new update should have landed for Everspace 2, but Galaxy seemed not unable to show it to me.
No matter what I tried (pause un pause downloads, search for update, close and re-start Galaxy), nothing.
I was at around 50% of Madmax (which means a lot of hours, my connection is capped to 0,3MB/s and I can't do anything about that), and what I feared was finally true : I had to cancel Madmax installation (and lost ~16 hours of downloading) simply to have the Everspace update appearing (another 32GB btw).

My question is : is that a known bug ? Is that some sort of timed out search error because my connection is too slow for Galaxy ?

And "of course", over the night I would have downloaded something like 6GB, and the "update failed" at 600MB. This is a pretty common error I got, not on every update, but it remains not rare, and no matter the size of the update.
I don't know what to do to prevent this...
