Welcome to HWS @Art_of_War
oh
Can you please send me your client log?
It is located here:
c:\Program Files (x86)\Steam\steamapps\common\Empyrion - Galactic Survival\Logs\3065\
Thanks, hopefully Eleon can fix this error.
I tried it very often myself and got never an exception.
So all I can ask for is to trash the duped Tokens of course and let me know if it happens again please.
