Sentinel-3 Synergy problem exporting to GeoTIFF


I’ve been having an issue where SNAP won’t export Sentinel-3 Synergy data to geotiff. Here’s what happened:

I’ve read in other topics that I should disregard the 0%, however, it’s been like this for 2 hours now. Does it normally take this long?
The image I’m trying to export is: S3A_SY_2_SYN____20181020T130423_20181020T130723_20181022T042040_0179_037_095_3240_LN2_O_NT_002.SEN3
Not sure if this is particular to S3 SYN or if it’s general.

Thanks in advance!
