Ok I've not been able to reproduce this bug for some reason but I've added a few more safeguards to hopefully make this problem less likely. Now published V1.1.3. If it still keeps happening can you please detail the exact circumstances leading up to the error? I.e. if it was during battle, flee sequence, trap, poison/disease effects etc?
The gem, it would have been the Onyx. Still I can't replicate this but now it could be because my latest fix has prevented it. So let me know if you spot this issue again after trying the latest version.
