I've been having a hair pulling issue where my scripts in my state machines keep losing their gameObject references.  I think Ive tracked it down to scripts that inherit from Odin's "SerializedMonoBehaviour".  Looks like every time I change something in one of those scripts, BOLT throws an error and reverts the link to "self".

InvalidOperationException: Missing target object for 'MonoTest.test'.

I don't have Odin but I intended on grabbing it soon; I'll investigate the issue then.

I'd need you to be more specific about some things though:

  • Are you sure it's only from Odin's scripts?
  • What do you mean by "change something in one of those scripts"?
  • Do you get that error in play mode or in the editor?

Went back to see if I could isolate it further to double check on your first point, and of course I couldn't trigger any issues for an hour...but then it suddenly happened again, and it does appear to be in Odin scripts.

By "change something in a script", its hard to determine, but it seems to be literally anything. For instance, changing my declared string from "Test" to "Test Test" and recompiling did the trick.

I thought it was in play mode only, but upon closer inspection I noticed an error that I had missed this time which did occur in edit mode after updating a script, hopefully it helps:

Hi NeedsLoomis,

Are you still getting this issue with Bolt v.1.0.5 and Odin v.1.0.5.1?

We've both been fixing many issues and this might have been fixed in the way.

If you still have problems, let me know and I'll talk to some of the Sirenix devs directly. Also, please send me a test scene where we can reproduce the bug.
