Reducing UNDO State Size

Okay, so these specific references would restore correctly from a game save file? A non-transient non-cache object storing a reference to a never-modified, preinit-cached, transient object?

I was wrong. It’s not fine since the properties that point to anything transient will be set to nil after a RESTORE.

So since you have properties that refer to the cache, don’t make the cache transient. Unless you can manually restore those properties in port-restore or post-restart code.

But you should probably do a simple test to see if the amount of undo steps changes with a transient cache or not. If not (or if the difference is small) then I’d say it’s not worth the extra effort.
