Coll and dict doesn't load file if placed in a subpatch

Hi guys.

Sometimes Max doesn't load data from files to dict or coll if the object is placed inside a subpatch. The workflow could look like:
1. Create coll in a root patch, populate it with data, save to file.
2. Copy the object to a subpatch or encapsulate it → Max window will print the error which states that there is no such file.
3. De-encapsulate or create another coll in the root patch → everything is OK.

Unfortunately, this heisenbug has disappeared when I started to make a minimal example patch demonstrating the problem.

So, have any of you encountered such such problem?

P.S. In fact I had a lot of weirdness with reading from the file system—files sometime just disappear from the path, but everything becomes OK after a restart.
