ive also got this issue.
It was caused when i tried to add an research (tried to add an shield research). It then created an error in an function (i think 2160, null pointer). Since it was recreating i thought it would be wise to save, and send the db. So i saved, closed game, and restarted to see if it reproduces, and now i get that 155 (null pointer). Seems like my race is gone, but dunno.
