I have observed this happen today, 20190830 on the Twitch stream for PATTIIIIIIII. Somebody crashed said streamer and all attempts to report that person were met with only a simple, uninformative statement that there was an error filing the report. It should be there on the end of the latest VoD, which may be a short one.

Can you provide more context? Does this occur 100% of the time? Are there steps necessary to perform before you'll get an error? Precisely what error message do you recieve? Can you attach an output log so we can take a closer look?
