Issue with CURIE syntax

[tr3vr]

Hi there, We've been using grefine and the CURIE syntax worked initally.
e.g. with prefix : eg and URI : http://lod.example.org/

The RDF preview showed the correct prefix, now for the past few days it doesn't work anymore.
Any suggestions would be awesome.

I've seen this behavior as well. If I remember correctly it happens when the prefix definitions disappear for a moment, although I can't remember how this happened.

I could "fix" it by simply entering the whole mappings again, which is for sure cumbersome.
