ShitTok or ProxiTok limits video playback to once, then if you refresh the page you only get an error "There was an error processing your request!" I have seen this about 3 times with ProxiTok so far, and I never got it to work more times than first access.
Process: . export+import CAR over SSH . export done, import in HPC <- was here last I checked . import done, pin in HPC <- happens quickly (maybe unneeded as default CAR import does this)
