bcftools csq throw sanity_check_ref error and could not pass by --force

Hi,

I kept on getting this error when running bcftools csq and it could not go past it even when supplied with --force. Could you help?

bcftools: csq.c:2801: sanity_check_ref: Assertion `vcf - rec->d.allele[0] < strlen(rec->d.allele[0]) && ref - TSCRIPT_AUX(tr)->ref < tr->end - tr->beg + 2*N_REF_PAD' failed.
Aborted

Thanks a lot!
