I'm testing the makeTxDbFromBiomart function, and I'm noticing that it seems to encounter an error, but only on the current version of Ensembl (85). Running it on version 84 works just fine. Is there a problem with the current Ensembl version's Biomart server, or the biomaRt package, or something else?

Are you still experiencing this issue? It works fine on my system with the same package versions. The ensembl BioMart servers have been a little temperamental for me recently, so maybe the archive host was performing more reliably?
I tried again today, and it worked this time. I thought for sure it was a bug and not a transient error, since I got the exact same error + traceback every time.
