Ok so i'm having the same issue, can't really tell what you said (even google trad can't because of it's crappy traduction) but i'm willing to solve it because it gets pretty annoying.
So i tryed a few things, reinstalling the game messing around with the serv batch to create a server before the game launch...
Well i could connect to the server but my character got wiped...
I looked a bit into the saves and the Player_1.dat file got "reset" with 128kB worth of 0
we messed around on the discord, in the avoriongamehelp channel and a bit in the general... but we are already 4-5 to have the same issue there...
I restarted the computer, had the firewall and anti-virus turned completly off and even though it doesn't whant to work on some of my galaxies... i can create a galaxie and play in it, but since that's already the 4rth time i restart the game.... Also connecting on a server doesn't work in some cases, again can't really tell, but sometimes i can, sometimes i can't... that's really weird... i don't think that's really gonna help you by much if you whant me to try something, i'll try to be there
I know that finding and fixing a bug is the worst part of software making... I really hope that we can do somthing about this one
