[Bioc-devel] No such file or directory: BSgenome.Hsapiens.UCSC.hg38/extdata/single_sequences.2bit

Warning in .seqlengths_TwoBitFile(x) : mustOpen: 
   Can't open /home/biocbuild/bbs-3.9-bioc/R/library/BSgenome.Hsapiens.UCSC.hg38/extdata/single_sequences.2bit 
   to read: No such file or directory 
   Timing stopped at: 0.176 0 0.175 Error in .seqlengths_TwoBitFile(x) : UCSC library operation failed

I get these errors almost every day - today on malbec2 (ubuntu) and tokay2 (windows). 

Any advice?
