Out of Memory Exception

[regularde]

So i've been getting this out of memory exception, which i saw the old posts about. Started happening when i clicked a prefab i was using, and unity suddenly started saving it (though i didn't change anything?).

In any case, it uses an external tree and i set it to use JSON serialization., with Allow edit of instances
When I place new instances of the prefab, there are no problems, but the problem is in the scenes where I've already placed instances of the prefab. When i select them or play, it freezes until i get the out of memory exception.

Is there any way to fix this? I'm not sure why only the old instances of the prefab have this issue.

So, i've sort of found a workaround, though like i said i only had this problem with older instances of the prefab. I ended up deleting the behavior tree component from the prefab so all instances across my scenes no longer had it, then readded it and set it up again. Now i no longer get this issue when i click the problematic instances.

Glad you found a solution. Based on the stack trace it looks like your tree is using binary serialization and when this happens generally the tree got corrupted in some way.
