I occasionally and regularly get the same problem when I try to use multileaders with a user-defined block which includes attributes. I insert the multi-leaders in my drawing, set the attributes, and go on my merry way. At some random point, which will be AFTER I have saved, closed and opened my drawing countless times over weeks of work, the block portion of my multi-leaders will suddenly lose their scale, and revert to 1, which makes them very tiny. The arrowhead remains properly sized. This usually happens after a refresh (not upon opening a drawing). I can't figure out what happened, or how to fix it. Help!
