Which version? You can press F1 and see (it’s on the last screen). If there’s no F1 help screen then it’s v1.0 and maybe a bug.
Might be a bug even in later versions? Can you give me any more info as to what you did, maybe? I’ll try to see if I can reproduce it. Did you properly get past the sand cat on the previous screen? ie: go through the few steps to run it off?
