Custom Line Styles in Reference Appear Different from Parent Model in Read-Only File

Hello!

We have a file where one model is referenced into another within the same file.  All [custom] line styles shown in the reference are completely different styles than how they appear in the parent model.  This is only the case when the file is opened Read-Only.  

  • There are no outside references that would affect this.
  • Re-importing line styles from the resource file does not fix it.
  • Level overrides are not being used, nor would they change the line style if it were to be set.
  • MS_SYMBRSRC is as it should be.
  • Compressing the file does not fix it.
  • I am unable to share the file.  [EDIT: see GNN.dgn in later post.]

Any idea what would be causing this?  It's unknown how old the seed file is that was used or if it began from a fresh DGN file.  For now, presume it isn't corrupt.

The file appears and can be printed fine if it isn't opened read-only.  The question is what's causing it in the first place?  This is an odd problem we haven't seen before.  It seems like one other forum post (118811) had the same problem, however it was left unanswered.

Thanks!
