Sorry for the inconvenience, it is fixed now in v1.8.3. You caught me just before I went to bed!
I don't understand what you mean by "breaking a dupped on reload spider tron", but from the log I could work out the incorrect logic, replicate it, and fix it.
well the only reason there was more then one spidertron was cus it dupped on mod reload and i wanting to get rid of it tried to feed the dupp to biters it both killed me and crashed the game
