I have several add-in commands that are using the InsertBlock2 function.  When the block being inserted contains an attribute that is a field, the drawing database becomes corrupted.  If enough blocks are added, the drawing will become unusable.  Inserting the same blocks from within DraftSight works perfectly.  The problem arises only from inserting through the API. 

Any DraftSight team members that can offer a workaround for this embedded problem?
