Hi, I think all white-box issues should be fixed now, but there may be some issues from people who had them earlier. if you delete the contents of this folder:
\my documents\my games\gratuitous space battles2\composites. That should fix it.
if it doesn’t, pls email me the debug file in
\my documents\my games\gratuitous space battles2\debug
