Re: initSwarm error?

[Rick Riolo]

Could this be because of the change in .swarmArchive format
that was introduced in some version change (I can't recall which)?
If you run *any* model compiled at or after that version,
and do a save on it, it creates a .swarmArchive file
that has a format that is not readable by earlier versions,
and in fact causes them to crash.
I think if you do the opposite (eg save under an earlier version,
then run a later version), it also causes the crash,
at initSwarm time, because that is when it reads the
.swarmArchiver file.

I believe you don't have to be running the same model
compiled under the different versions....they all read
the same .swarmArchiver file and have the same problem.

It might be nice to put into future swarms a more
graceful detection of the wrong format...
